ON LICHENICOLOUS FUNGI FROM CONTINENTAL NORTH-AMERICA

An annotated list of lichenicolous fungi from continental North America is presented. The fifty-eight taxa listed (fifty-three ascomycetes and five coelomycetes) include two species new to science: Lichenochora xanthoriae Triebel & Rambold and Sphaerellothecium subtile Triebel & Rambold. Two combinations are made: Arthonia subfuscicola (Lindsay) Triebel [bas. Microthelia subfuscicola Lindsay] and Stigmidium congestum (Koerb.) Triebel [bas. Pharcidia congesta Koerb.]. Twenty-seven lichenicolous fungi are reported as new for the flora of continental North America. Additional host species are reported for twenty-three taxa.
