摘要 基于形态学和分子证据，对来自东亚的 Trechisporales 的四个新种 Dextrinocystiscalamicola、Subulicystidiumacerosum、S.tropicum 和 Tubuliciumbambusicola 进行了描述和说明。 Trechisporales 的系统发育是从 ITS-nrLSU 序列的组合数据集中推断出来的。在系统发育树中，Sistotremastrum 形成了自己的科级进化枝，是所有其他属形成的 Hydnodontaceae 进化枝的姐妹。 Dextrinocystis，首次被证实为 Hydnodontaceae 的成员。给出了 Trechisporales 中所有公认属的索引。
Abstract Four new species in Trechisporales from East Asia, Dextrinocystiscalamicola, Subulicystidiumacerosum, S.tropicum and Tubuliciumbambusicola, are described and illustrated, based on morphological and molecular evidence. The phylogeny of Trechisporales was inferred from a combined dataset of ITS-nrLSU sequences. In the phylogenetic tree, Sistotremastrum formed a family-level clade of its own, sister to the Hydnodontaceae clade formed by all other genera. Dextrinocystis, is for the first time, confirmed as a member of Hydnodontaceae. A key to all the accepted genera in Trechisporales is given.
