Two new species in the lichen genus Atla, A. alaskana and A. recondita, are described. The ITS rDNA region is used for their molecular characterization. Morphologically, Atla alaskana is characterized by its rather thick and well-developed whitish grey thallus, and the rather large perithecia having a thalline excipulum. The presence of a thalline excipulum renders it similar to Sporodictyon species; however, in A. alaskana a distinct zone around the ostiolum is without a thallus and covered only by a thick white pruina. Atla recondita has a thin olivaceous brown thallus and moderately sized, emerging perithecia. It is not possible to identify this species unequivocally as an Atla species only by morphology, and it might well be mistaken for a Polyblastia. A key to all six Atla species, including the two new species, is provided.
