During our survey of the diversity of woody litter fungi in China and Thailand, three species were collected from dead woody twigs of sp. (Dipterocarpaceae) and (Boraginaceae). Both morphology and multigene analyses revealed two taxa as new species ( and ) and the remaining collections as new records of . is characterized by 1) dimorphic conidia, having circular to oval lenticular conidia and 2) turbinate conidia consisting of two columns with two septa composed of 2-3 cells in each column. is characterized by dimorphic conidia, having circular to oval lenticular conidia and clavate or subcylindrical to cylindrical conidia and consisting of one or two columns with 6-8 cells in each column. Phylogenetic analyses of combined LSU, ITS, 2, 1-α and 2 sequence data supports the placement of these new taxa within Hermatomycetaceae with high statistical support.
在我们对中国和泰国木本凋落物真菌多样性的调查中，从龙脑香科的 属和紫草科的 属的枯木小枝上采集到了三个物种。形态学和多基因分析表明，其中两个分类单元为新物种（ 和 ），其余的采集样本为 的新记录。 的特征为：1）双态分生孢子，具有圆形至椭圆形的透镜状分生孢子；2）陀螺形分生孢子，由两列组成，每列有两个隔膜，每个隔膜由2 - 3个细胞组成。 的特征为双态分生孢子，具有圆形至椭圆形的透镜状分生孢子以及棒状或近圆柱形至圆柱形的分生孢子，由一列或两列组成，每列有6 - 8个细胞。对 LSU、ITS、2、1 - α 和 2 序列数据进行联合系统发育分析，以较高的统计支持率支持了这些新分类单元在间座壳科中的分类地位。
