Microcalicium arenarium (Hampe ex A. Massal.) Tibell

A calicioid fungus, growing on colonies of Stichococcus algae and on thalli of lichens from the genus Psilolechia, mainly P. lucida. Microcalicium arenarium seeks after microclimatically stable, humid but rain-protected microhabitats, such as uprooted trees and rock overhangs. In Europe and in the Czech Republic, it occurs sparsely at various elevations. Probably, it is an overlooked species.
