Hymenochaete liyiriana sp. nov. (Hymenochaetaceae, Basidiomycota) from Arunachal Pradesh, Northeast India

A new polypore, Hymenochaete liyiriana T. Rakhe & R. K. Singh, is described based on its morphological and molecular characterisation. It was collected from the sub-tropical forest of Arunachal Pradesh (India) that lies within the Eastern Himalaya biodiversity hotspot. H. liyiriana is characterised by a concentrically lamellate hymenophore, tramal hyphae with hooked tip, and cyanophilous basidiospores. The internal transcribed spacer (ITS) and partial nc 28S rDNA (nLSU) region-based phylogenetic analysis also differentiated H. liyiriana from the closely related species, H. campylopora and H. setipora.
