    Thamnolia tundrae sp nov., a cryptic species and putative glacial relict2018In: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135, Vol. 50, no 1, p. 59-75Article in journal (Refereed)
    Abstract [en]

    The lichen species of the genus Thamnolia, with their striking wormlike thalli and frequent occurrence in arctic and tundra environments, have often been debated with regard to the use of chemistry in lichen taxonomy. Phylogenetic studies have arrived at different conclusions as to the recognition of species in the genus, but in a recent study based on the analyses of six nuclear markers (genes or noncoding regions) of a worldwide sample of Thamnolia, we showed the existence of three well-supported lineages with two different chemistries and geographical distributions. Here, we present two analyses based on ITS and three markers, respectively, which were extended from the study mentioned above to include type specimens and additional Thamnolia strains and taxa. In these analyses the same three clades were retrieved. A putative DEAD-box helicase is used here for the first time as an informative phylogenetic marker to provide taxonomic resolution at species level. The distribution of morphological and chemical characters across the phylogeny was analyzed and it was concluded that three morphologically cryptic, but genetically well supported, species occur: T. vermicularis s. str., T. subuliformis s. str. and T. tundrae sp. nov. Thamnolia vermicularis s. str. contains individuals with uniform secondary chemistry (producing thamnolic acid) and a rather limited distribution in the European Alps, Tatra Mts and the Western Carpathians, a distribution which might result from glacial survival in an adjacent refugium/refugia. Thamnolia subuliformis s. str. is widely distributed in all hemispheres and the samples contain two chemotypes (either with thamnolic or squamatic acids). Thamnolia tundrae is described as new; it produces baeomycesic and squamatic acids, and has a distribution limited to the arctic tundra of Eurasia extending to the Aleutian Islands in North America. It may have survived the latest glaciation in coastal refugia near its present distribution. Thus, secondary chemistry alone is not suitable for characterizing species in Thamnolia, secondary chemistry and geographical origin are informative, and the ITS region can be confidently used for species recognition. Nomenclatural notes are given on several other names that have been used in Thamnolia.

    Molecular and morphological data place Blarneya in Tylophoron (Arthoniaceae)2011In: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135, Vol. 43, no 4, p. 345-356Article in journal (Refereed)
    Abstract [en]

    Based on morphological, anatomical, chemical, ecological and molecular evidence, Blarneya is synonymized here with Tylophoron. The molecular phylogeny derived from sequences obtained from sporodochia of Blarneya places this genus, described to accommodate an anamorphic lichen with white cushion-shaped sporodochia, within Tylophoron. This conclusion is further supported by the discovery of Tylophoron-type ascomata emerging directly from thalli with Blarneya-type sporodochia and producing identical hyaline conidia. In one specimen pycnidia were also observed. This represents a surprising variety of morphologically different conidiomata. A different anamorphic type was previously reported from Tylophoron, and this is confirmed here by molecular analysis for T. moderatum: besides thalli with ascomata this species has anamorphic thalli with an irregularly delimited brown sporodochial felt and brown conidia. Ascomata are not known from these entirely anamorphic thalli, whereas they do occur infrequently in Tylophoron species with Blarneya-type sporodochia. A key to all currently accepted species of Tylophoron is provided. In addition to the corticolous Tylophoron hibernicum, confined to humid forests, two saxicolous species with Blarneya-type sporodochia are described here as new: T. galapagoense, known only from Galapagos, differs from T. hibernicum by a thicker, more compact, beige rather than white, more strongly C+ red thallus, growing below sheltered rock overhangs in dry forests; T. stalactiticum has a C- thallus with stipitate, white, C+ red sporodochia; the species is known only from a single locality in Tenerife, on a large slope with volcanic boulders.

    Eurotiomycetes: Eurotiomycetidae and Chaetothyriomycetidae2006In: Mycologia, ISSN 0027-5514, E-ISSN 1557-2536, Vol. 98, no 6, p. 1053-1064Article in journal (Refereed)
    Abstract [en]

    The class Eurotiomycetes (Ascomycota, Pezizomycotina) is a monophyletic group comprising two major clades of very different ascomycetous fungi: (i) the subclass Eurotiomycetidae, a clade that contains most of the fungi previously recognized as Plectomycetes because of their mostly enclosed ascomata and pyototunicate asci; and (ii) the subclass Chaetothyriomycetidae, a group of fungi that produce ascomata with an opening reminiscent of those produced by Dothideomycetes or Sordariomycetes. In this paper we use phylogenetic analyses based on data available from the Assembling the Fungal Tree of Life project (AFTOL), in addition to sequences in GenBank, to outline this important group of fungi. The Eurotiomycetidae include producers of toxic and useful secondary metabolites, fermentation agents used to make food products and enzymes, xerophiles and psychrophiles, and the important genetics model Aspergillus nidulans. The Chaetothyriomycetidae include the common black yeast fungi, some of which are pathogens of humans and animals, as well as some primarily lichenized groups newly found to be phylogenetically associated with this group. The recently proposed order Mycocaliciales shows a sister relationship with Eurotiomycetes. The great majority of human pathogenic Pezizomycotina are Eurotiomycetes, particularly in Eurotiales, Onygenales and Chaetothyriales. Due to their broad importance in basic research, industry and public health, several genome projects have focused on species in Onygenales and Eurotiales.

    Generic classification of the Verrucariaceae (Ascomycota) based on molecular and morphological evidence: recent progress and remaining challenges2009In: Taxon, ISSN 0040-0262, E-ISSN 1996-8175, Vol. 58, no 1, p. 184-208Article, review/survey (Refereed)
    Abstract [en]

    Recent molecular phylogenetic analyses and morphological Studies have shown that it is necessary to revise the present morphology-based generic delineation of the lichen family Verrucariaceae in order to account for evolutionary relatedness between species. Consequently, several genera were recently described or resurrected, and others were re-circumscribed. As an additional step toward this generic revision, three new genera (Hydropunctaria, Parabagliettoa, Wahlenbergiella) and eleven new combinations are proposed here. A summary of the Current taxonomic and morphological circumscription of all genera investigated so far is also presented. Several monophyletic groups are identified for which further taxonomical changes will be required, but for which taxon and gene sampling is presently viewed as insufficient. Clear morphological synapomorphies were found to be rare for newly delimited genera. In some cases (reduced morphology or plesiomorphism), even the combinations of slightly homoplasious phenotypic characters do not allow a clear morphological generic circumscription. Molecular features are envisioned as characters for delimiting these taxa.

    Racoleus, a new genus of sterile filamentous lichen-forming fungi from the tropics, with observations on the nomenclature and typification of Cystocoleus and Racodium2011In: IMA Fungus, ISSN 2210-6340, E-ISSN 2210-6359, Vol. 2, no 1, p. 71-79Article in journal (Refereed)
    Abstract [en]

    Racoleus trichophorus gen. sp.  nov. is described for a ;tropical sterile filamentous lichenized fungus which overgrows various crustose lichens on bark. It shares some features with Cystocoleus and Racodium, but is unique in having non-lichenized arcuate lateral spines. The genus, which is known from China, the Ivory Coast, and Peru, is of uncertain systematic position; on the basis of morphological similarities, however, it may be referred to "? Capnodiales (incertae sedis)" ad interim. In addition, the nomenclature and typification of the monotypic genera Cystocoleus and Racodium are reviewed, and lectotypes selected for the type of each. The available information on the ecology and distribution of these two genera is also summarized, and scanning electron micrographs (SEM) of all three species are presented for the first time.

    A higher-level phylogenetic classification of the Fungi2007In: Mycological Research, ISSN 0953-7562, E-ISSN 1469-8102, Vol. 111, no 5, p. 509-547Article, review/survey (Refereed)
    Abstract [en]

    A comprehensive phylogenetic classification of the kingdom Fungi is proposed, with reference to recent molecular phylogenetic analyses, and with input from diverse members of the fungal taxonomic community. The classification includes 195 taxa, down to the level of order, of which 16 are described or validated here: Dikarya subkingdom nov.; Chytridiomycota, Neocallimastigomycota phyla nov.; Monoblepharidomycetes, Neocallimastigomycetes class. nov.; Eurotiomycetidae, Lecanoromycetidae, Mycocaliciomycetidae subclass. nov.; Acarosporales, Corticiales, Baeomycetales, Candelariales, Gloeophyllales, Melanosporales, Trechisporales, Umbilicariales ords. nov. The clade containing Ascomycota and Basidiomycota is classified as subkingdom Dikarya, reflecting the putative synapomorphy of dikaryotic hyphae. The most dramatic shifts in the classification relative to previous works concern the groups that have traditionally been included in the Chytridiomycota and Zygomycota. The Chytridiomycota is retained in a restricted sense, with Blastocladiomycota and Neocallimastigomycota representing segregate phyla of flagellated Fungi. Taxa traditionally placed in Zygomycota are distributed among Glomeromycota and several subphyla incertae sedis, including Mucoromycotina, Entomophthoromycotina, Kickxellomycotina, and Zoopagomycotina. Microsporidia are included in the Fungi, but no further subdivision of the group is proposed. Several genera of 'basal' Fungi of uncertain position are not placed in any higher taxa, including Basidiobolus, Caulochytrium, Olpidium, and Rozella.

    Chaenotheca longispora (Coniocybaceae), a new lichen from coast redwood trees in California, USA2019In: The Bryologist, ISSN 0007-2745, E-ISSN 1938-4378, Vol. 122, no 1, p. 31-37Article in journal (Refereed)
    Abstract [en]

    Chaenotheca longispora is described as a new species from the central coast of California, U.S.A. It is similar in morphology to C. laevigata but is distinguished by the long (up to 25 mu m) and spirally ornamented ascospores as well as chemically by the PD+ orange and K+ yellow reaction of the thallus. Thus far, C. longispora has been collected only from the crowns of large coast redwood (Sequoia sempervirens) trees in Armstrong Redwoods State Natural Reserve, where it occurs on the thick, fibrous bark of the trunks. A key to Chaenotheca species in North America, including C. longispora, is provided.

    Two new Aspicilia species from Fennoscandia and Russia2011In: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135, Vol. 43, no 1, p. 27-37Article in journal (Refereed)
    Abstract [en]

    Aspicilia fluviatilis and A. granulosa, two arctic and/or (sub) alpine species with elongate +/- diverging and +/- branching marginal areoles, are described as new and compared with similar species occurring in Fennoscandia. A parsimony analysis based on ITS indicates a close relationship with the mainly coastal A. epiglypta. Aspicilia epiglypta, A. disserpens and A. sublapponica are lectotypified and A. disserpens is reduced to synonymy with A. perradiata. Aspicilia alboradiata and A. circularis are excluded from the Fennoscandian lichen biota. A key to Fennoscandian Aspicilia species with radiating thalli and/or elongate +/- diverging and +/- branching marginal areoles is also presented.

    Phylogeny and taxonomy of Aspicilia and Megasporaceae2010In: Mycologia, ISSN 0027-5514, E-ISSN 1557-2536, Vol. 102, no 6, p. 1339-1349Article in journal (Refereed)
    Abstract [en]

    Phylogenetic analyses based on nuLSU and mtSSU indicate that Megasporaceae is monophyletic. Aspicilia species were distributed among three main well supported groups and one group with low support that included the type species; a division of the family into five genera is proposed. The old names Circinaria and Sagedia are reintroduced for groups not including A. cinerea, the type of Aspicilia. The monotypic Megaspora is closely related to Circinaria, while Lobothallia is the sister group of the other Megasporaceae genera. Aspicilia recedens and A. farinosa are transferred to Lobothallia. Species of the 'Sphaerothallia group' are nested in Circinaria. Aspilidea is not a member of Megasporaceae but seems to be more closely related to Ochrolechiaceae. Aspilidea myrinii is neotypified, and lectotypes are designated for Aspicilia gibbosa, A. leprosescens and Lecanora gibbosula.

    Abstract [en]

    A preliminary molecular phylogeny of 26 Aspicilia species based on nuclear rDNA ITS1-5.8S-ITS2 is presented and compared with the occurrence of some morphological features and secondary chemical products. Three major monophyletic groups were discovered, one including aspicilin-containing species with large spores and short conidia, a second with mainly arctic-alpine species with small spores, variable chemistry and conidium length, and a third group having spores of variable size, conidia of medium size and containing β-orcinol depsidones. An extended analysis of the second subgroup, including additional species and sequences, resulted in the synonymization of a number of names. Lectotypes are designated for A. mashiginensis, A. mastrucata, A. obscurata and A. permutata, and the lectotypification of A. verruculosa is discussed.

    Abstract [en]

    The new name Aspicilia berntii is proposed to accomodate Lecanora mastoidea Lynge in Aspicilia and a lectotype is designated. Additional characters are added to the species description and a comparison is made with similar species. The species is reported as new to Scandinavia with localities in northern Norway. An assessement of the phylogenetic relationships, based on a split network analysis of ITS sequences, places A. berntii close to A. verrucigera in the A. cinerea group

    A worldwide phylogeography of the whiteworm lichens Thamnolia reveals three lineages with distinct habitats and evolutionary histories2017In: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758, Vol. 7, no 10, p. 3602-3615Article in journal (Refereed)
    Abstract [en]

    Thamnolia is a lichenized fungus with an extremely wide distribution, being encountered in arctic and alpine environments in most continents. In this study, we used molecular markers to investigate the population structure of the fungal symbiont and the associated photosynthetic partner of Thamnolia. By analyzing molecular, morphological, and chemical variation among 253 specimens covering the species distribution range, we revealed the existence of three mycobiont lineages. One lineage (Lineage A) is confined to the tundra region of Siberia and the Aleutian Islands, a second (Lineage B) is found in the high alpine region of the Alps and the Carpathians Mountains, and a third (Lineage C) has a worldwide distribution and covers both the aforementioned ecosystems. Molecular dating analysis indicated that the split of the three lineages is older than the last glacial maximum, but the distribution ranges and the population genetic analyses suggest an influence of last glacial period on the present-day population structure of each lineage. We found a very low diversity of Lineage B, but a higher and similar one in Lineages A and C. Demographic analyses suggested that Lineage C has its origin in the Northern Hemisphere, possibly Scandinavia, and that it has passed through a bottleneck followed by a recent population expansion. While all three lineages reproduce clonally, recombination tests suggest rare or past recombination in both Lineages A and C. Moreover, our data showed that Lineage C has a comparatively low photobiont specificity, being found associated with four widespread Trebouxia lineages (three of them also shared with other lichens), while Lineages A and B exclusively harbor T. simplex s. lat. Finally, we did not find support for the recognition of taxa in Thamnolia based on either morphological or chemical characters.

Nash III on his 65th Birthday / [ed] Scott T. Bates et al., Berlin/Stuttgart: J. Cramer , 2011, p. 235-246Chapter in book (Refereed)
    Abstract [en]

    Circinaria arida sp. nova is described from the Sonoran area. In the Sonoran Desert Lichen Flora 3 it was tentatively treated as Aspicilia desertorum. This name, however, is based on Lecanora desertorum, an illegitimate name introduced by Krempelhuber for both vagrant and saxicolous taxa, but usually only applied to non-vagrant, saxicolous specimens. In the analysis presented here these are shown to represent more than one taxon. For American specimens the epithet elmorei is available, and the combination Circinaria elmorei is proposed.

    Aspicilia goettweigensis (Megasporaceae, lichenized Ascomycetes) – a poorly known and overlooked species in Europe and Russia2017In: Nordic Journal of Botany, ISSN 0107-055X, E-ISSN 1756-1051, Vol. 35, no 5, p. 595-601Article in journal (Refereed)
    Abstract [en]

    Aspicilia goettweigensis is a poorly known species from xerothermic siliceous rocks in Europe. It is considered to be common in the Czech Republic and it is new to Hungary and Russia. The main diagnostic character is formation of cracked, popcorn-like, areoles in the central parts of the thalli. Analysis of nrITS sequences revealed its close relationship to Aspicilia subdepressa and A. volcanica. TLC revealed stictic acid in analysed A. goettweigensis samples. A key to non-lobate Aspicilia with stictic acid known from Europe is provided.

    Molecular phylogeny of the genus Lecania (Ramalinaceae, lichenized Ascomycota)2007In: Mycological Research, ISSN 0953-7562, E-ISSN 1469-8102, Vol. 111, no 5, p. 581-591Article in journal (Refereed)
    Abstract [en]

    The molecular phylogeny of the lichen genus Lecaniawas investigated using nucleotide sequences from the mt-SSU rRNA, the ITS region of the nu-rDNA, and the RNA polymerase II second largest subunit. Forty-six species representing Lecania and other genera likely to influence the phylogeny were included in the study. Phylogenetic reconstructions were carried out using Bayesian inference, ML, and MP approaches. Lecania, as traditionally circumscribed, is not a monophyletic genus. However, a monophyletic group containing a large number of Lecania species, including the type species L. fuscella, was discovered in the analysis, and recognition of Lecania sensu stricto is suggested. L. baeomma, L. glauca, L. gerlachei, L. brialmontii, L. racovitzae, L. hyalina (alias Biatora globulosa), L. chlorotiza, L. naegelii, and L. furfuracea do not belong in Lecania s. str., although the latter two are closely related to Lecania s. str. Representatives of the genus Bilimbia form a well-supported group, as does the ‘Thamnolecania’ group containing the Antarctic ‘Lecania’ species, L. gerlachei, L. brialmontii, and L. racovitzae. An alternative to recognizing these two genera would be a wider circumscription of Bilimbia to include the ‘Thamnolecania’ group as well as affiliated taxa.

    Polyblastia in Northern Europe and the adjacent Arctic2012Book (Other academic)
    Abstract [en]

    Polyblastia s.str. (Verrucariaceae, Chaetothyriomycetidae) of Northern Europe and the adjacent Arctic is revised. The morphology and the history of the exploration of Polyblastia s.str. is described. Twenty-five species are recognized, twelve of them being new. A molecular phylogeny of the genus based on the internal transcribed spacers (ITS) of nuclear ribosomal DNA is presented and compared with earlier suggestions on infrageneric classification. Polyblastia s.str. is compared with related and similar genera, and the traditional delimitation of genera inthe Verrucariaceae is discussed. A key to the species is given and the morphology, ecology and distribution of the species are described along with notes on synonymy and nomenclature. Lectotypes of 13 taxa have been designated and comments on additional species frequently referredto Polyblastia in 20:th century lichenological literature from the area have been included.

    The lichen genus Henrica (Verrucariaceae, Eurotiomycetes) in northern Europe2008In: Nordic Journal of Botany, ISSN 0107-055X, E-ISSN 1756-1051, Vol. 26, no 3-4, p. 237-247Article in journal (Refereed)
    Abstract [en]

    In a previous three gene phylogeny study (nuITS rDNA, nuLSU rDNA and RPB1 region A-D) a well supported clade, most closely related to Verrucaria rupestris and also close to Sporodictyon and Atla, was found. Here this clade is identified as Henrica. A phylogeny of these genera based on the nuITS rDNA is supplied, and also a key to crustose species in Verrucariaceae with large, brown muriform spores. Based on material from northern Europe, Henrica is emended to include H. theleodes and H. melaspora, both new combinations in the previously monotypic genus. Verrucaria theleodes and V. scotinospora are lectotypified.

    Abstract [en]

    A list of lichens from Serbia is presented, comprising species not earlier known from Serbia and species that have been recorded once or a few times only. It also includes a few lichenicolous fungi. The list is based on investigations of material in the lichen collection of the Belgrade Natural History Museum, and material collected by the authors. In all 70 species of lichens and eight lichenicolous fungi are reported from Serbia for the first time. The lichen genera Brodoa, Cornicularia, Hypocenomyce, Lobothallia, Pycnora, Pyrenocollema, Rhizoplaca, Rinodinella, Schaereria, Solenopsora, and Trapelia, and the lichenicolous genera Abrothallus, Carbonea, Cercidospora, Lichenodiplis, Muellerella, Scutula, and Vouxiella are new to Serbia. For 17 lichen species (previously recorded without any locality indication), first localities from Serbia are given. Additional localities are given for 77 species, for which only a few localities have been published.

    Atla, a new genus in the Verrucariaceae (Verrucariales)2008In: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135, Vol. 40, no Part 4, p. 269-282Article in journal (Refereed)
    Abstract [en]

    The new genus Atla forms a well-supported clade in a molecular phylogeny based on the ITS1-5.8S-ITS2 and LSU regions of the nuclear ribosomal DNA. The genus has a crustose thallus, a hamathecium at maturity without hyphal elements except for pseudoparaphyses remaining at the ostiolum, and large, muriform spores. Atla wheldonii was previously referred to Polyblastia. Three new species, A. alpina (the type of the new genus), A. palicei and A. praetermissa, are included in the genus and described here as new to science. They were found on calcareous rocks and soil in Northern Scandinavia, A. alpina also occurs in Central Europe, and A. wheldonii likewise in Central Europe, the Pyrenees and in the British Isles. An identification key to the species and a revision of the genus are also provided.

    Taxonomy and species delimitation in Sporodictyon (Verrucariaceae) in Northern Europe and the adjacent Arctic – reconciling molecular and morphological data2009In: Taxon, ISSN 0040-0262, E-ISSN 1996-8175, Vol. 58, no 2, p. 585-605Article in journal (Refereed)
    Abstract [en]

    Morphological variation in Sporodictyon is scrutinized in an effort to   reconcile it with monophyletic groups based oil molecular evidence.   Molecular data (nucITS, nucLSU, RPBI) are investigated by Bayesian and parsimony phylogenetic analyses, statistical parsiniony, and split   decomposition. Morphological variation within and between the   monophyletic groups is evaluated. Four monophyletic groups strongly  Supported by Molecular data correspond to morphologically well-characterized species. Sporodictyon schaererianum and S. terrestre   are morphologically variable, especially with respect to thallus   structure. Two distinct subclades are found in both species, but they   could, however, not be distinguished morphologically and may be   regarded as cryptic species. A combination of ascoma size, spore   pigmentation, spore size and thallus structure characterizes the   species recognized, whereas thallus thickness, involucrellum thickness   and excipulum pigmentation are found to be quite plastic. A taxonomic revision of Sporodictyon Northern Europe and the adjacent Arctic is   provided, recognizing five species. Two new species, S. arcticum and S.   minutum, are described. The name Polyblastia theleodes has been  misapplied for S. schaereriamum. Several taxonomic synonyms are   proposed, particularly for S. terrestre, and lectotypes for several species names are designated.

    Abstract [en]

    Phylogenetic relationships of the lichen genus Polyblastia and closely related taxa in the family Verrucariaceae (Verrucariales, Chaetothyriomycetidae) were studied. A total of 130 sets of sequences (nuLSU rDNA, nuITS rDNA and RPB1 region A-D), including 129 newly generated sequences, were analysed. Phylogenetic relationships were inferred using a Bayesian approach based on two datasets. A first analysis of a larger, two-locus dataset (nuLSU and RPB1) for 128 members of the Verrucariaceae, confirmed the polyphyly of Polyblastia, Thelidium, Staurothele, and Verrucaria, as currently construed. The second analysis focused on 56 Polyblastia and allied taxa, but using an additional locus (nuITS rDNA) and two closely related outgroup taxa. The latter analysis revealed strongly supported groups, such as Polyblastia s. str., the Thelidium group (a mixture of Polyblastia, Thelidium, Staurothele and Verrucaria species). The genus Sporodictyon, which is here accepted, also accommodates Sporodictyon terrestre comb. nov. Morphological features traditionally used for characterizing Polyblastia, Thelidium, Staurothele and Verrucaria, such as spore septation and colour, occurrence of hymenial photobiont, involucrellum structure, and substrate preference, were found to be only partially consistent within the strongly supported clades, and thus are not always reliable features for characterizing natural groups.

    Phylogeny of the subgenus Eumitria in Tanzania2019In: Mycology: An International Journal on Fungal Biology, E-ISSN 2150-1211Article in journal (Refereed)
    Abstract [en]

    Several Usnea species in subgenus Eumitria (Parmeliaceae, lichenized Ascomycota) have been described from East Africa in the past decades. These have been based on morphology and chemistry data while molecular studies remain very limited. In this paper we are for the first time publishing phylogenetic analyses along with morphological and chemical data for Eumitria. ‬A total of 62 new sequences of Eumitria (26 ITS, 20 nuLSU, 6 MCM7, 10 RPB1) were generated in this study. nuLSU, MCM7 and RPB1 sequences are here for the first time reported for U. baileyi. A phylogeny of subgenus Eumitria from Tanzania based on Bayesian and maximum likelihood analyses of a concatenated four-loci data set is presented, confirming the monophyly of Eumitria. Further, secondary chemistry and variation in characters, such as the pigmentation of the central axis and branch shape were investigated.
