Abstract
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.
Jørg. & Palice, Parmeliella psoromoides P.M. Jørg. & Palice, Psoroma cinnamomeum ssp. andinum P.M.
Jørg. & Palice and Santessoniella macrospora P.M. Jørg. & Palice.
