Taxonomy, phylogeny and ecology of a new bambusicolous Resupinatus species (Agaricales, Resupinataceae) from Northern Thailand

The exploration of the fungal diversity associated with bamboos in Northern Thailand has yielded a hitherto undescribed species, Resupinatus reviviscens sp. nov. It is characterized by brownish grey to dark grey basidiomata, basal hairs forming an off-white to yellowish grey subiculum-like felt and composed of hyphae that are thin-walled near the apex and thick-walled near the base, broadly ellipsoid to ellipsoid basidiospores, lack of cheilocystidia and presence of clavate pleurocystidia, and habitat on bamboo culms.

Additionally, it has distinct ITS sequences and forms a supported species-level clade separated from other Resupinatus species as revealed by the ML phylogenetic analysis combining ITS and LSU sequences.
