The Coniocybaceae are the sole family of lichen-forming fungi in the Coniocybales, which itself is the only order in the class Coniocybomycetes.

Pseudothelomma is a genus of crustose pin lichens in the family Caliciaceae. It contains two species. The genus was established in 2016 when DNA analysis revealed that two species previously classified in the genus Thelomma were actually distinct and formed their own separate evolutionary group. These lichens are distinguished by their preference for growing on dry, bark-free conifer wood and their black, flat spore-bearing structures that may have a greenish-yellow powdery coating.

Allocalicium is a single-species fungal genus in the family Caliciaceae. It is monotypic, containing the single pin lichen species Allocalicium adaequatum. This lichen occurs in North America, South America, Europe, and the Russian Far East, where it grows on branches and twigs of deciduous trees and shrubs, typically those of alder and poplar. The species was originally described in 1869 as a member of Calicium, but molecular phylogenetics analysis demonstrated it was not a member of that genus and so Allocalicium was created to contain it. Allocalicium is characterised by a thallus that

Lichinodium is a genus of filamentous lichens. It is the only genus in the family Lichinodiaceae, itself the only member of the order Lichinodiales. Lichinodium has four species. Previously considered part of the class Lichinomycetes, molecular phylogenetic analysis revealed that Lichinodium represents a unique lineage in the Leotiomycetes—the first known group of lichen-forming fungi in this class.

Pseudothelomma ocellatum is a species of lignicolous (wood-dwelling), crustose lichen in the family Caliciaceae. This lichen is characterised by its grey, areolate thallus that produces abundant lichenised diaspores, such as short spherical isidia and coarse, dark brown-black soredia. It is typically sterile, meaning apothecia (fruiting bodies) are absent. Pseudothelomma ocellatum is primarily a Northern Hemisphere lichen, especially found in temperate to cool temperate areas, and somewhat rare in North America where its range has expanded from southern California to the Yukon since its first

Pseudothelomma occidentale is a species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. It was first formally described by Albert William Herre in 1910, who initially classified it in the genus Cyphelium. Leif Tibell transferred it to Thelomma in 1976. In 2016, María Prieto and Mats Wedin transferred the taxon to the newly circumscribed genus Pseudothelomma. In his original description of the lichen, Herre identified Cyphelium occidentalis as a new species, previously determined as an Acolium species by Hasse in 1902. He described the thallus as determinate, forming

Clavascidium lacinulatum is a dark brown squamulous terricolous lichen. In Joshua Tree National Park, it is the most common of the biological soil crust lichens. It is notable for its ability to withstand UVC ultraviolet radiation for extended periods of time.

Calicium pinicola is a species of lignicolous (wood-dwelling), crustose lichen in the family Caliciaceae. It is widely distributed in Europe, and also occurs in the United States.

Calicium carolinianum is a species of lichen in the family Caliciaceae. It is endemic to the Gulf Coastal Plain region of the United States. The lichen contains norstictic acid, and has ascospores that measure 13–17 by 8–9 μm.

Bunodophoron crespoae is a species of ground-dwelling, fruticose lichen in the family Sphaerophoraceae. It is found in the Páramo of south-east Colombia, growing in association with moss.
