A new species, new combination, and a nomen novum in the genus Trechispora from India

Abstract

The genus Trechispora accommodate species with corticioid, clavarioid, and polyporoid basidiomata, smooth to verrucose, angular basidiospores, monomitic or dimitic hyphal systems with clamp-connections, and ampullaceous septa. During a study of clavarioid fungi of Kerala, seven Trechispora species with clavarioid basidiomata were collected and studied. Morphological and molecular analyses revealed one species, T. cystidiata, characterized by cystidia, to be new to science. In addition, a new combination (T. angulispora) and a nomen novum (T. corneri) are also proposed. Descriptions of all the species collected and studied from Kerala, along with their phylogenetic placement in the order Trechisporales is presented. A taxonomic key to the clavarioid species of Trechisporales from India is also provided.
