Abstract

Five new species of Clavulina (Clavulinaceae, Cantharellales, Basidiomycota) are described from the Pakaraima Mountains of Guyana, occurring in rain forests dominated by the ectomycorrhizal tree Dicymbe corymbosa (Caesalpiniaceae). These clavarioid fungi have simple (i.e., unbranching) basidiomata, which is a relatively uncommon phenotypic feature for the genus Clavulina. Macromorphological, micromorphological, and habitat data are provided for each taxon, and nuclear ribosomal DNA sequences of the 28S subunit and internal transcribed spacer region were obtained for each holotype collection.
