Arthoniomycetes are a class of ascomycete fungi. It includes the single order Arthoniales. Most of the taxa in this class are tropical and subtropical lichens.

[edit] Systematics

Phylogenetic analysis supports the monophyly of this class.^[1] Doditheomycetes is a sister group.^[2]

[edit] Characteristics

Taxa have apothecia, cup- or saucer- shaped ascoma in which the hymenium is exposed at maturity. These apothecia are bitunicate - with clearly differentiated inner and out walls.
