, a new genus to accommodate , and a new species (Xerocomoideae, Boletaceae) from Thailand.

A new genus, is established to accommodate based on multiple protein-coding genes (6, 3, 1, and 2) analyses of a wide taxon sampling of Boletaceae. In our phylogeny, the new genus was sister to in subfamily Xerocomoideae, phylogenetically distant from , which was highly supported as sister to in the same subfamily Xerocomoideae. is different from other genera in Boletaceae by the following combination of characters: rugulose to subrugulose pileus surface, white pores when young becoming pale yellow in age, subscabrous stipe surface scattered with granulose squamules, white basal mycelium, unchanging color in any parts, yellowish brown spore print, and broadly ellipsoid to ellipsoid, smooth basidiospores. In addition, , also from subfamily Xerocomoideae, is newly described. Detailed descriptions and illustrations of the new genus and new species are presented.
