The lignicolous Buellia carballaliana Paz-Bermúdez & Giralt is described as new from Portugal. It is characterized by a thickly crustose to subsquamulose, milk-coffee colored thallus which contains 5-O-methylhiascic acid, and small, unornamented ascospores, belonging to the Buellia-type when mature but showing septal wall thickenings during a brief period of the spore ontogeny ( = Physconia-type), and always with a well-developed torus.
