Lichen subclasses

Agaricomycetidae is a subclass of fungi, in the division Basidiomycota. The name Agaricomycetidae had previously been named by Marcel Locquin in 1984, but his publication did not contain a Latin diagnosis and it is therefore invalid under the International Code of Nomenclature for algae, fungi, and plants. It was subsequently validly published by Erast Parmasto in 1986.

Dothideomycetidae is a fungal subclass in the class Dothideomycetes The cavities of the sexual structures do not have vertical cells (paraphyses, pseudoparaphyses or paraphysoids) growing between the sac-like cells bearing the sexual spores (asci).

Sordariomycetidae is a subclass of sac fungi.

Chaetothyriomycetidae is a subclass of ascomycete within the class Eurotiomycetes. Many species in Chaetothyriomycetidae are lichens.
