本文报道了三个新种，即右旋粉盘菌Aleurodiscus dextinoideophyses，粉盘菌A. thailandicus和A.本文从形态学和分子生物学的角度对竹类植物的疣孢霉进行了描述和说明。Aleurodiscus dextrinoideophyses和A. thailandicus，采自泰国北方，具有丰富的棘突和小而光滑的担孢子，属于A. cerussatusgroup.而A. dextrinoideophyses的特征是具有糊精状的棘藻，A. Thailandicus在子实层下和基层之间有黄色的棘突。疣孢粉盘菌（Aleurodiscus verrucosporus）采自中国东南部的福建省，其特征是无刺藻和疣状担孢子。三种真菌均具有丰富的胶囊菌和单隔的生殖菌丝。根据ITS和nrLSU序列数据推断了甜菊科植物的亲缘关系。在系统发育分析中，A. dextrinoideophyses和A. thailandicus稳定地嵌套在A. cerussatus组，而A.在最大简约法和贝叶斯分析中，疣孢壳属与不同的分类群聚在一起。
Three new species, Aleurodiscus dextrinoideophyses, A. thailandicus and A. verrucosporus, on bamboos are described and illustrated based on morphological and molecular evidence. Aleurodiscus dextrinoideophyses and A. thailandicus, collected from northern Thailand, possess abundant acanthophyses and small smooth basidiospores, and belong to the A. cerussatus group. While A. dextrinoideophyses is characterized by the dextrinoid acanthophyses, A. thailandicus has yellow acanthophyses arranged between subhymenium and basal layer. Aleurodiscus verrucosporus, collected from Fujian Province, southeastern China, is distinguished by the absence of acanthophyses and verrucose basidiospores. All the three species have abundant gloeocystidia and simple-septate generative hyphae. The phylogeny of taxa in Stereaceae was inferred from the combined ITS and nrLSU sequence data. In our phylogenetic analyses, A. dextrinoideophyses and A. thailandicus steadily nested within the A. cerussatus group, whereas A. verrucosporus clustered with different taxa in maximum parsimony and Bayesian analyses.
