The Ostropomycetidae are a subclass of mostly lichen-forming fungi in the class Lecanoromycetes. It contains nine orders and 37 families.

Megaspora is a genus of lichen-forming fungi in the family Megasporaceae. It contains four species of crustose lichens that typically grow on soil, bryophytes (mosses and liverworts), or plant litter on chalky .

Lobothallia is a genus of lichen-forming fungi in the family Megasporaceae. Dark brown to black apothecia may be sunken into the surface of the thallus, as indicated in the common name puffed sunken-disk lichen. Originally described as a subgenus of Aspicilia in 1984, Lobothallia was elevated to full genus status in 1991 based on distinctive features including peripheral and small, thin-walled ascospores. The genus was established to clarify a group of rock-dwelling lichens that had previously been classified across several different genera.

Bellemerea is a genus of saxicolous (rock-dwelling) crustose lichens in the family Lecideaceae. These lichens form tough, crusty patches on hard rock surfaces, often appearing as a mosaic of small angular blocks in colours ranging from white and grey to brown. The genus includes nine species found primarily in mountainous and polar regions where they help colonize bare rock surfaces in harsh environments.

Clauzadeana is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed in 1984 by Claude Roux, with the crustose species C. instratula assigned as the type.
