Sarcogyne albothallina is a species of rock-dwelling, crustose lichen-forming fungus in the family Acarosporaceae. It was formally described as a new species in 2016 from specimens collected from the Missouri Breaks region of Montana. It is differentiated from others in Sarcogyne by its white, non-powdery thallus and by the presence of 4-O-methylhiascic acid, a combination of features that separates it from other species sharing a blackened upper spore-bearing surface (carbonized epihymenium).

Opegrapha vulpina is a species of lichenicolous (lichen-eating) fungus in the family Opegraphaceae. It is found in the Czech Republic, Dobruja, Romania, and the Italian Apennine Mountains. It grows parasitically on two species of saxicolous (rock-dwelling), crustose lichens.

Endococcus thelommatis is a species of lichenicolous (lichen-dwelling) fungus in the family Lichenotheliaceae. It was formally described as a new species in 2011 by the lichenologists Jana Kocourková and Kerry Knudsen. The fungus grows on the lichen Thelomma santessonii, a common saxicolous (rock-dwelling), crustose lichen that is endemic to the coast and islands of Southern California and Mexico's Baja California. Endococcus thelommatis is the first lichenicolous fungus to have been reported from this lichen.

Acarospora brodoana is a species of saxicolous (rock-dwelling) crustose lichen in the family Acarosporaceae. It was described as a new species in 2016 from specimens collected in the San Bernardino Mountains in southern California. The type specimen was collected on granite from a steep terraced slope above the cirque near Dollar Lake. The species epithet honors the lichenologist Irwin M. Brodo. The lichen is distinguished from similar species by the combination of a blackened upper ascospore-bearing surface (carbonized epihymenium) and a black tissue layer beneath the spore-bearing region

Trimmatothelopsis sphaerosperma is a species of crustose lichen in the family Acarosporaceae. Originally described in 2011 as Acarospora sphaerosperma from dolomite in Arkansas, it was transferred to the genus Trimmatothelopsis in 2021 based on morphological and anatomical features, because DNA sequencing attempts were unsuccessful in that treatment. The species forms scattered waxy white areoles (small surface patches) with small red-brown apothecial discs and is distinguished by its tall hymenium (spore-bearing layer); asci that contain more than 100 mostly spherical ascospores; and long,
