Anamorphs of 17 taxa in the genus Umbilicaria (Lecanorales, Ascomycotina)a re connected with known teleomorphs through what is described as the thallic type of connection. Teleomorphs of Umbilicaria aprina Nyl. and Umbilicaria cinerascens (Arnold) Frey are described for the first time. Possible correlated trends in the evolution of anamorphs and teleomorphs are discussed.
