Catapyrenium boccanum

Catapyrenium boccanum is a species of squamulose (scaley), rock-dwelling lichen in the family Verrucariaceae. It grows on mortar or on calcareous rock. Its squamules are up to 4 mm wide, pale to dark brown with black margins and a black underside. Ascospores measure 11–15 by 5–8 μm.[3] Because of its combination of squamulose thallus, simple ascospores (without any septa), and lack of algae in the hymenium, this species is a "catapyrenioid" lichen, of which more than 80 exist in the Verrucariaceae.[4]

The lichen was first formally described as a new species in 1955 by Czech lichenologist Miroslav Servít.[5] Othmar Breuss transferred it to Catapyrenium in 1990 as part of a revision of that genus.[6] In Europe, the lichen has a largely Mediterranean distribution, although scattered records are known from western and southern Europe.[3] It is also found in Turkey.[7]
