Ahtiana
Ahtiana is a genus of lichenized fungi in the family Parmeliaceae. A monotypic genus, it contains the single species Ahtiana sphaerosporella, found in western North America. This species was segregated from the genus Parmelia by Canadian lichenologist Trevor Goward in a 1985 publication. It had been suggested that the genus include A. aurescens and A. pallidula based on similarities in morphology, but this transfer is not supported by molecular analysis.
The genus was named in honour of Finnish botanist Teuvo Tapio Ahti.
