Psilolechia

Psilolechia is a genus of four species of crustose lichens. It is the only member of Psilolechiaceae, a family that was created in 2014 to contain this genus.

==Taxonomy== The genus Psilolechia was established by Abramo Bartolommeo Massalongo in 1860. Formerly classified in the family Pilocarpaceae (now Ectolechiaceae), molecular phylogenetic analysis showed that Psilolechia represented a distinct lineage that deserved placement at the familial level, the Psilolechiaceae, which was formally circumscribed in 2014. This arrangement was accepted in later large-scale updates of fungal classification. Psilolechiaceae is in the order Lecanorales, in the suborder Sphaerophorineae, which also includes the families Ectolechiaceae, Psoraceae, and Ramalinaceae.
