Basidiolichen

Biogeographically, basidiolichen species may be distributed in a cosmopolitan manner or more regionally, ranging from arctic and montane habitats to more temperate and tropical environments.

Other genera include Acantholichen, Arrhenia, Athelia, Athelopsis, Corella, Cyphellostereum, Ertzia, Lepidostroma, Lichenomphalia, Marchandiomphalina, Semiomphalina, and Sulzbacheromyces.

In basidiolichens of the genera Acantholichen, Cora, and Dictyonema, photobionts may be penetrated by hyphal tips called haustoria and thereby assimilated into the complete lichen thallus.

In species of Athelia, Athelopsis, Cyphellostereum, Lepidostroma, and especially Multiclavula, the association takes the form of globular photobiont clusters ensheathed by fungal hyphae.

Within the genus Cora, fruiting bodies are often lobed and may be glabrous (smooth and glossy) or setose (bristly), ranging in color from green to white.
