Absconditella

Genus of lichen-forming fungi

Absconditella is a genus of lichen-forming fungi in the family Stictidaceae. These lichens are characterised by their inconspicuous growth and small, cup-shaped fruiting bodies (apothecia) that are often hidden within a jelly-like mass containing green algae. The genus name, meaning "hidden", reflects their elusive nature. Absconditella species are typically found on short-lived surfaces such as decaying wood, mosses, and unstable soil. Genetic studies have revealed that the genus is more complex than previously thought, with some species being moved to a new genus, Absconditonia, and others potentially representing groups of closely related species. Despite their small size and easily overlooked nature, environmental DNA studies suggest that Absconditella lichens may be more widespread than collections indicate.
