Pteridicolous ascomycetes from a cloud forest in eastern Mexico

Abstract

Twenty-one ascomycetous taxa collected on ferns in a cloud forest of Veracruz, Mexico are reported and described. Fourteen represent new records for the Mexican mycobiota: Bisporella pteridicola, Crocicreas quinqueseptatum, Dasyscyphella dryina, Durella macrospora, Hamatocanthoscypha helicotricha, Hyaloscypha fuckelii, Lachnum brevipilosum, L. nudipes, Mollisia ventosa, Orbilia auricolor, Protocreopsis pertusa, Seimatosporium tostum, Stictis carnea, and S. radiata. Two collections—Cyathicula and cf. Arachnopeziza—that could not be fully identified may represent new species. The remaining five taxa have previous Mexican records but are reported here from new fern hosts. This study increases to 25 the number of ascomycete species known to occur on ferns in the cloud forests of Mexico.
