Abstract
Xerocomus doodhcha and Hortiboletus indorubellus (Boletaceae) from broadleaf montane forest in Sikkim, India, are proposed as new. They are described in detail with supporting morphological illustrations and compared with related taxa using molecular phylogenetic analysis of ITS and 28S rDNA sequences. Xerocomus doodhcha is characterized by a pale brown pileus, basidiospores with a finely bacillate surface under SEM, and phylogenetic proximity to the type species of Xerocomus, X. subtomentosus Hortiboletus indorubellus is characterized by a dark brown to reddish brown pileus, context that turns brownish to brownish orange on bruising, and phylogenetic proximity to Hortiboletus rubellus.
