, a new bolete genus from tropical forests of Thailand is introduced with . as the type species. The genus is unique among Xerocomoideae in producing dark ruby spore deposits. It can be differentiated from all other Boletaceae genera by the following combination of characters: pileus surface evenly covered with matted tomentum; stipe surface with evenly scattered minute squamules; golden yellow tubular hymenophore, which is relatively thin especially when young; unchanging surfaces and context when bruised or cut; smooth, broadly ellipsoid basidiospores; and dark ruby spore deposits. The Boletaceae-wide and Xerocomoideae-wide phylogenetic analyses based on four-gene data sets (6, 3, 2, and 1) support as monophyletic and places it in Boletaceae subfamily Xerocomoideae. Full descriptions and illustrations of the new genus and species are presented.
本文描述了一个来自泰国热带森林的新牛肝菌属，以[具体物种名]为模式种。该属在牛肝菌亚科中独特之处在于产生深红宝石色的孢子印。它可通过以下特征组合与所有其他牛肝菌科属区分开来：菌盖表面均匀覆盖着交织的绒毛；菌柄表面有均匀散布的微小鳞片；金黄色的管状菌褶，尤其是幼嫩时相对较薄；受伤或切割后表面和菌肉不变色；光滑、宽椭圆形的担孢子；以及深红宝石色的孢子印。基于四基因数据集（6、3、2和1）的全牛肝菌科和牛肝菌亚科系统发育分析支持该属为单系类群，并将其置于牛肝菌科牛肝菌亚科中。文中给出了新属和新物种的完整描述及图示。
