Abstract

A novel cupulate basidiomycete fungus was discovered during a survey of mangrove-associated fungi in Chanthaburi and Phetchaburi Provinces, Thailand. This species, found exclusively on decaying Rhizophora mucronata hypocotyls in intertidal zones, forms minute fruiting bodies and shows close morphological and molecular resemblance to Calathella mangrovei Jones & Agerer, 1992. Phylogenetic analyses of ITS and LSU rDNA regions confirmed its placement within Calathella, as a distinct sister lineage to C. mangrovei. Therefore, these isolates represent a novel species, for which the name Calathella sirindhorniae sp. nov. is proposed.
