Catalogue of Life  Wikipedia  MycoBank  A new genus, Rubroboletus, to accommodate Boletus sinicus and its allies– KUAN ZHAO, GANG WU & ZHU L. YANG – Phytotaxa 188 (2): 061–0771 (2014)- (Abstract – Rubroboletus is erected as a new genus to accommodate Boletus sinicus and its allies based on morphological and molecular evidence. Morphologically, Rubroboletus differs from the remaining genera in Boletaceae by the combination of a reddish pileal surface, an orange-red to blood red surface of the hymenophore, yellow tubes, pink to red reticula or spots on the yellow background of the stipe, a bluish color-change when injured, a non-amyloid context, smooth spores which are olivebrown in deposit, and an interwoven trichodermal pileipellis. Our phylogenetic analyses based on five gene markers (ITS, nrLSU, tef1-α, rpb1 and rpb2) recognized eight species in the genus, including one new species and seven new combinations. A key to the eight species is provided.)
