在对中国热带地区带孢菌属（Polyporales, Basidiomycota）和Grammothele （Grammothele denticulata）标本的调查中，通过形态学和系统发育分析，鉴定出3个新种：膜带孢菌属（theeleporus membranaceus）、小带孢菌属（T. minisporus）和齿状带孢菌属（Grammothele denticulata）。对它们进行了描述和说明。其特征是极薄的担子果（0.12 mm），小孔（每mm 7-10个）和椭圆形至宽椭圆形的担子孢子。小孢子绦虫的担子孢子在本属物种中最小。在本属中，小齿Grammothele denticulata的特征是灰色气孔，分离边缘上连续的膜层和圆柱形的担子孢子，顶端渐细。为目前已被接受的两种提供了带注释的鉴定键。根据nITS序列推断了Theleporus和Grammothele的系统发育关系，并对其进行了简要讨论。分子证据表明，细孔门和Grammothele属核心多孔门分支。
During the examination of specimens of Theleporus and Grammothele (Polyporales, Basidiomycota) from tropical China, three new species, Theleporus membranaceus, T. minisporus and Grammothele denticulata, were identified based on both morphological and phylogenetic analyses. They are described and illustrated. T. membranaceus is characterized by its extremely thin basidiocarps (0.12 mm), small pores (7–10 per mm) and ellipsoid to broadly ellipsoid basidiospores. T. minisporus has the smallest basidiospores among the species in the genus. Grammothele denticulata is distinguished in the genus by gray pores, continuous hymenia over dissepiment edge and cylindrical basidiospores with tapering apex. Two annotated identification keys are provided for species thus far accepted in Theleporus and Grammothele. The phylogenetic relationships of Theleporus and Grammothele were inferred based on nITS sequences and are briefly discussed. The molecular evidence showed that Theleporus and Grammothele belong to the core polyporoid clade.
