Abstract

Eleven species of Inocybe, a highly diverse genus of ectomycorrhizal Agaricales, are documented from tropical India in Kerala State. Seven species are described as new. Furthermore, I. pileosulcata is reported from India for the first time. I. virosa, not previously validated, is validated here. Gross morphological and microscopic descriptions, illustrations, and phylogenetic affiliations are provided. Seven species feature nodulose or spinose basidiospores and belong to the Inocybe clade. The remaining four species are characterized by the combination of smooth spores and absence of pleurocystidia. Two of these share an alliance with the Pseudosperma clade, and the other two with the Inosperma clade. All 11 species likely share an ecological association with lowland tropical Dipterocarpaceae. The new combination I. mucidiolens is made (formerly I. calamistrata var. mucidiolens).
