Physconia
Physconia is a genus of lichen-forming fungi in the family Physciaceae. It comprises 13 species. The genus was established in 1965 by the lichenologist Josef Poelt and is characterized by leaf-like growth forms with lobes typically less than 3 mm wide that often have a whitish, powdery coating on their tips. These lichens can be distinguished from similar genera by their distinctive brown ascospores that have thick walls, fine warts, and a single dividing wall but lack the end thickenings found in related groups.
