描述了采自中国南方的牛肝菌目（Boletales）牛肝菌科（Boletaceae）牛肝菌目（Boletales）牛肝菌属（Tylopilus callainus）一新种。其形态特征为：菌盖褐色，略带海绿色，被损伤时，子实梗和内梗呈海绿色，菌柄上部呈海绿色，外表皮菌盖，菌丝稍膨大。28 S区部分序列、核rDNA内转录间隔区（ITS）和翻译延伸因子1-α基因（TEF 1）的系统发育分析也证实了T. callainus在Tylopilus s中形成了一个独立的谱系。并对新鲜担子瘤进行了详细的描述、彩色照片和显微结构的线画。
Tylopilus callainus (Boletaceae, Boletales) is described as a new species from the south of China. It is morphologically characterized by a brown pileus tinged with sea-green, a sea-green color change of hymenophore and context when injured, a stipe with sea-green color on the upper part, and a trichodermal pileipellis with slightly inflated hyphae. Phylogenetic analyses of DNA sequences from partial 28S regions, the nuc rDNA internal transcribed spacer (ITS) and the translation elongation factor 1-α gene ( TEF1 ) also confirm that T. callainus forms an independent lineage within Tylopilus s. str. Consequently, a detailed description, color photos of fresh basidiomata and line-drawings of microstructures are presented.
