PRIETO, M.; ARAGON, G.  e  MARTINEZ, I.. New records in the lichen family Verrucariaceae (Ascomycota) from Argentina. Bol. Soc. Argent. Bot. [online]. 2008, vol.43, n.3-4, pp.205-210. ISSN 1851-2372.

Four interesting lichens belonging to Catapyrenium, Placidium and Placopyrenium genera (Verrucariaceae) were collected for the first time in Argentina. Catapyrenium exaratum was only reported from Chile and Perú. Placidium acarosporoides was previously known from North America, Chile and South Africa. Placidium pilosellum, a widespread and common species, but little known in South America. Finally, Placopyrenium bucekii, a mediterranean-submediterranean lichen, represents a new record from South America. For these taxa we provide a brief description with emphasis on the ecological aspects and distribution maps.
