描述了三种新发现的裂孔菌属（Schizophoraceae）菌丝齿菌属（Hyphodontia）。中国丝齿菌（Hyphodontia chinensis sp. nov.）nov.分布于日本中部和台湾北方，具孔状子实膜柄，突出的栓状结构，囊壁具壳; subtropica sp. nov.采自中国云南省和越南北方，具孔状的子实梗，顶部微膨胀的囊孢子，假二分菌丝系统。利用最大简约法和贝叶斯方法构建了基于ITS序列的系统发育树。每个新种的独立地位是基于形态学研究，进一步证实了ITS为基础的系统发育分析。最近提出的H. dimitica与H.根据形态学和分子生物学证据，
Three species of Hyphodontia (Schizoporaceae) with poroid or raduloid hymenial surface are described as new to science. Hyphodontia chinensis sp. nov. was found in southwest and northeast China, having raduloid hymenophore, ventricose to subulate cystidia, and slightly thickened-walled, ellipsoid basidiospores; H. reticulata sp. nov. was found in central Japan and northern Taiwan, having poroid hymenophore, projecting peg-like structures, and encrusted cystidia; H. subtropica sp. nov. was collected from China (Yunnan province) and northern Vietnam, having poroid hymenophore, slightly apically swollen cystidioles, and pseudodimitic hyphal system. Both maximum parsimony and Bayesian methods were used to construct the phylogenetic trees based on ITS (internal transcribed spacer) sequences. The independent status of each proposed new species is based on morphological study, further confirmed by ITS-based phylogenetic analysis. The recently presented H. dimitica is found to be conspecific with H. nongravis, based on morphological and molecular evidences.
