摘要：

A new species of Clavulina (Clavulinaceae, Cantharellales, Basidiomycota) is proposed from the Atlantic Forest of Santa Catarina, Southern Brazil. Clavulina junduensis fits the generic concept of Clavulina in having coralloid, branched basidiomata and basidia with two cornute sterigmata. This species is characterized by purplish-gray basidiomata, brownish-orange stipe, and context with abundant gloeopleurous hyphae with refringent content and bulbous swellings. We provide a detailed morphological description of the species and illustrations of the basidiomata as well as a comparison with morphologically similar taxa. Phylogenetic analyses of Clavulina junduensis and related species were carried out based on the sequences of internal transcribed spacer region of the nuclear ribosomal RNA gene (nrITS). The phylogenetic results support the placement of our specimens within the genus Clavulina and confirm its distinctiveness from morphologically similar species. A key to Clavulina species from Brazil is also provided.
