Anaptychia

Anaptychia is a genus of lichen-forming fungi in the family Physciaceae. Anaptychia species are foliose (leafy) to fruticose (bushy) lichens. They have brown, thin-walled spores with a single septum, and a upper .

==Taxonomy== The genus was circumscribed by German lichenologist Gustav Wilhelm Körber in his 1848 work Grundriss der Kryptogamen-Kunde. In his 1962 monograph on the genus, Syo Kurokawa included 88 species. A few years later, Josef Poelt thought the genus should be divided into two genera – Anaptychia and Heterodermia – based largely on differences in spore structure. William Culberson supported this opinion, emphasizing the presence of distinct chemical characteristics between the two groups.
