利用核糖体大亚基RNA（nrLSU）、翻译延伸因子apha-1（tef 1-a）和RNA聚合酶II最大亚基（rpb 1）的分子数据库，揭示了中国南方短牛肝菌属（牛肝菌目，牛肝菌科）的两个谱系。其中一个与以前基于形态特征的分类群相对应，即长颈牛肝菌（Boletelluslongicollis），另一个与基于形态特征描述的分类群不同。因此，本文对棒金牛肝菌Auroboletusclavatussp. nov.和棒金牛肝菌A. longicollis comb. nov.提供了详细的描述，彩色照片的新鲜担子，和线条画的显微镜特征的两个类群。
Two lineages of Aureoboletus (Boletales, Boletaceae) from southern China were revealed by using molecular data based on combined dataset of the nuclear ribosomal large subunit RNA (nrLSU), the translation elongation factor apha-1 ( tef1-a ) and the largest subunit of RNA polymerase II ( rpb1 ). One of them corresponds with the previous morphology-based taxon, viz. Boletellus longicollis , another one is different from those taxa described based on morphological features. And, thus, Auroboletus clavatus sp. nov. and A. longicollis comb. nov. were proposed. A detailed description, colour photos of fresh basidiomata, and a line-drawing of microscopic features of the two taxa were provided.
