摘要
Collections from high altitudes (3840-5100 m a.s.l.) have added several species to the Pannariaceae of Ecuador: Fuscopannaria praetermissa, Pannaria hookeri, Psoroma paleaceum and Psoroma tenue are new to the Andes, and phytogeographic consequences of these are discussed. The following new taxa are described: Parmeliella corallina P. M. Jorg. & Palice, Parmeliella psoromoides P. M. Jorg. & Palice, Psoroma cinnamomeum ssp. andinum P. M. Jorg. & Palice and Santessoniella macrospora P. M. Jorg. & Palice. They are part of a high-andean element which is not well known and is indicative of a migration route between the polar regions. In addition, two species with associated cyanobacteria, as the primary or secondary symbiont, are reported for the first time from South America: Thelignya lignyota (Wahlenb.) P. M. Jorg. & Henssen and Pilophorus cereolus (Ach.) Th. Fr, both originating from the Northern Hemisphere.
