Psoroma is a genus of lichenized fungi in the family Pannariaceae.[4] The genus was circumscribed by French botanist André Michaux in 1803.[5] The widespread genus contains an estimated 58 species, most of which are found in south temperate regions.[6] Some species formerly in Psoroma were transferred to the new genera Psorophorus and Xanthopsoroma in 2010.[7] The genus Joergensenia was erected in 2008 to contain the species formerly known as Psoroma cephalodinum.[8]
