Rhodocybe brunneoaurantiaca (sect. Rufrobrunnea, Entolomataceae): A new species from India

We describe a new species of Rhodocybe, R. brunneoaurantiaca, from West
Bengal, India. Field photographs of the collected basidiocarps
are provided and the new species is compared with its allied taxa
based on morphological and molecular (nrITS and nrLSU sequence)
data. Rhodocybe brunneoaurantiaca is characterized by
clitocyboid basidiomata with a small (25–41 mm), infundibuliform,
brownish orange to brown pileus; decurrent, brittle, greyish
orange to light brown lamellae; a smooth light brown to brown
stipe; ellipsoid to broadly ellipsoid basidiospores; 2–4-spored
basidia; cylindrical to slender clavate, flexuous cheilocystidia;
and unique sequences. A full description with illustrations, and
phylogenetic trees showing the placement of the new species based
on molecular sequence data are provided as well as an artificial
key to the reported species of Rhodocybe from India.
