Hemiaustroboletus, a new genus in the subfamily Austroboletoideae (Boletaceae, Boletales).

ABSTRACT: The present study describes Hemiaustroboletus gen. nov. in the subfamily Austroboletoideae (Boletaceae). Hemiaustroboletus is supported by morphological and molecular data using LSU and RPB2 regions. Additionally, its geographic distribution and intraspecific variation were inferred using ITS sequences. The genus is characterised by pileate-stipitate basidiomata; purple, brown, reddish-brown, orange-brown to dark brown vinaceous pileus; whitish or lilac to vinaceous context and a subclavate stipe. Microscopically, it is characterised by ornamented, slightly verrucose, cracked to perforated brown basidiospores. Two species are described within the genus, Hemiaustroboletusvinaceobrunneus sp. nov. and H.vinaceus sp. nov. Hemiaustroboletusvin
