Stigmatochroma is a genus of lichenized fungi in the family Caliciaceae. The genus has a widespread distribution, and contains 9 species.

Endohyalina is a genus of 10 species of corticolous (bark-dwelling) crustose lichens in the family Caliciaceae. These lichens either form thin, tightly attached crusts on tree bark or live as parasites on other lichens, sometimes becoming so reduced that they are nearly invisible to the naked eye. They produce small, black, disc-shaped fruiting bodies that begin buried in the crust and later emerge flush with the surface, containing spores that are divided once by a cross-wall and darken to brown as they mature.

Baculifera is a genus of lichens in the family Caliciaceae. It was circumscribed in 2000 by Bernhard Marbach and Klaus Kalb. Species in this genus are characterized by having bacilliform conidia typically measuring 8–11 μm long, and a non-inspersed hymenium. The genus is roughly similar in morphology to Buellia.

Cratiria is a genus of lichen-forming fungi in the family Caliciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 20 species. The genus was circumscribed by Austrian lichenologist Bernhard Marbach in 2000, with Cratiria lauri-cassiae assigned as the type species.

Sculptolumina is a genus of corticolous lichens in the family Caliciaceae. The genus was circumscribed by Bernhard Marbach in 2000, with Sculptolumina japonica designated as the type species.

Hafellia gomerana is a species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. It is found in the Canary Islands. It has a creamy white-coloured thallus, and unique microscopic and chemical characteristics.

Hafellia alisioae is a rare species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. Found in the Canary Islands, it was formally described as a new species in 2003 by Javier Etayo and Bernhard Marbach. The species epithet alisioae is derived from alisios, the Spanish word for the moisture-laden Atlantic winds that blow from the northeast, bringing high humidity and rain to exposed coasts with biodiverse lichen growth. Mireia Giralt and Pieter P.G. van den Boom proposed to transfer the taxon to the genus Buellia in 2011.

Fluctua is a lichen genus in the family Caliciaceae. It is monotypic, containing the single crustose lichen species Fluctua megapotamica. The genus was circumscribed by Austrian lichenologist Bernhard Marbach in 2000. It was one of several segregate genera proposed by Marbach in his 2000 revision of American species of Buellia. The lichen is found in Brazil and Uruguay.
