Calatayud, V.Navarro Rosinés, PereHafellner, J.2013-06-272013-06-272013-06-022077-7000https://hdl.handle.net/2445/44473A study on the taxonomy, morphology and anatomy of the lichenicolous species of the genus Cercidospora (Dothideales, incertae sedis) growing on lichens of the genera Lecanora (Lecanoraceae), specifically of the L. polytropa group and the L. saxicola group (i.e. L. muralis sensu auct. group, Protoparmeliopsis spp.), Rhizoplaca (Lecanoraceae) and Squamarina (Stereocaulaceae) is presented. The following species are proposed as new: Cercidospora barrenoana on Rhizoplaca peltata, and C. melanophthalmae on Rhizoplaca melanophthalma. C. stenotropae is proposed provisionally; this fungus grows on Lecanora stenotropa and other taxa of the L. polytropa group. A key for the species of the genus Cercidospora treated is provided.19 p.application/pdfeng(c) Mushroom Research Foundation , 2013Taxonomia botànicaLíquensFongsBotanical taxonomyLichensFungiinfo:eu-repo/semantics/article5678642013-06-27info:eu-repo/semantics/openAccess
