The 2016 classification of lichenized fungi in the Ascomycota and Basidiomycota – Approaching one thousand genera

Ninety years after Zahlbruckner, we present the most recent update to the classification of lichen fungi in the Ascomycota and Basidiomycota to genus level, with species numbers and references to changes compared to the 2010 Outline of Ascomycota and other recent classifications. Updated statistics on global species richness of lichen fungi and species richness at family, order and class level are given. The number of accepted species is 19,387 in 995 genera, 115 families, 39 orders and eight classes. Lichenized Basidiomycota amount to 172 species (0.9% of the total), 15 genera (1.5%), five families (4.3%), five orders (12.8%) and one class (12.5%). The most speciose genera are Xanthoparmelia, Lecanora,…
