New species of Clavulina (Cantharellales, Basidiomycota) with resupinate and effused basidiomata from the Guiana Shield

Journal Article

Three new species of Clavulina (Cantharellales, Basidiomycota) are described from rainforests dominated by ectomycorrhizal trees of the leguminous genus Dicymbe (Fabaceae subfam. Caesalpinioideae) from the central Guiana Shield. Species of Clavulina typically form branched, coralloid basidiomata with amphigenous hymenia. However, the three species described here form resupinate or effusocoralloid basidiomata, macromorphological forms previously unknown in Clavulina. Macromorphological, micromorphological, habitat and DNA sequence data are provided for each new species. Micromorphological features and DNA sequence data from the second largest subunit of DNA-dependant RNA polymerase II (rpb2) and internal transcribed spacer (ITS) and large subunit (28S) of the ribosomal repeat justify placement of these new species in Clavulina. Comparisons with described Clavulina species and other resupinate taxa within the Cantharellales are provided. © 2012 by The Mycological Society of America.
