Crocinoboletus是牛肝菌科的一个新属，包括红金牛肝菌Boletus rufoaureus和B. laetissimus，其特征在于其由不寻常的boletocrocin多烯色素的存在引起的担子瘤的明亮的橙子颜色，当挫伤时所有部分都是蓝色的橄榄色染色，光滑的担子孢子，以及在菌盖中部具有交织的中胚层和在菌盖边缘具有表皮的菌盖。先前的分子系统发育分析也证实了这两个类群不是牛肝菌属的成员，但在牛肝菌科内形成了一个得到充分支持的属谱系。本文对Crocinoboletus与近缘类群进行了描述、彩色照片、显微结构的线画和比较。
Crocinoboletus is described as a new genus of Boletaceae to accommodate Boletus rufoaureus and B. laetissimus, characterized by its brilliant orange color of basidiomata caused by the presence of unusual boletocrocin polyene pigments, bluish olivaceous staining of all parts when bruised, smooth basidiospores, and the pileipellis which has an interwoven trichoderm at the middle part of the pileus and a cutis at the margin of the pileus. Prior molecular phylogenetic analyses also confirmed the two taxa are not members of the genus Boletus ss, but form a well-supported generic lineage within Boletaceae. Consequently a description, color photos of fresh basidiomata, line-drawings of microstructures and a comparison of Crocinoboletus with allied taxa are presented.
