The genus in its enlarged circumscription includes species with disciform ascomata, non-amyloid hymenial gel, strongly amyloid, 1-2-spored asci, and 1- or 2-celled ascospores with thick, 1-layered walls. All species contain lecanoric acid, and may also contain lichexanthone or variolaric acid. Currently, we accept seven species in this genus. The accepted names and authorities are listed below.
