Systematics

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

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.

gollark: A beesolang, if you will.
gollark: What about an actor-model esolang with bees?
gollark: Feature idea for some random esolang: using diacritics to modify behavior of operators in some way?
gollark: Yes, although the unprintable lang never went anywhere.
