Abstract


Inocybe gregaria sp. nov. is described from Kerala State, India, based on morphological and molecular data. A comprehensive description, photographs, and comparisons with phenetically similar and phylogenetically related species are provided. The nuclear ribosomal internal transcribed spacer region (nrITS), a portion of the nuclear ribosomal large subunit (nrLSU) and a portion of the nuclear second-largest subunit of RNA polymerase II (rpb2) gene of this species were sequenced and analyzed. BLASTn searches using LSU and rpb2 sequences and subsequent ML phylogram of combined LSU and rpb2 sequences revealed that I. gregaria is conspecific with Inocybe sp. ZT8944, a collection assigned to the Inosperma clade that remains undescribed.
