Fellhaneropsis almquistiorum S. Ekman, a lichenized ascomycete in the family Pilocarpaceae (Lecanorales, Lecanoromycetes) is described as new to science. It is characterized by the thin and filmy crustose thallus, small photobiont, apothecia with a yellowish to black disk and well developed black margin that becomes excluded with age, dark green and brown pigmentation in the proper exciple and hypothecium, a hymenium without pigment or with some green and brown pigment, more or less fusiform and 3-septate ascospores, abundant black pycnidia, and long and filiform conidia. The species is currently known from central Sweden and central Germany, where it inhabits shaded and acid to neutral rocks with few competing lichens. Historical records were all misidentified as Bacidia coprodes or any of its synonyms or misapplied names. Some specimens of F. almquistiorum contain a previously unrecorded pigment, tentatively named here Almquistiorum-yellow. This pigment is intensely golden yellow in water, does not react with KOH and fades with the addition of HCl or HNO3. A key to all known, pycnidiate members of Fellhaneropsis is provided.
