In the present study, we investigate taxonomy of the Auriculariales with effused or cupulate, persistent basidiocarps; generic and species concepts are revised based on morphological and DNA evidences. The genus Eichleriella is reinstated to embrace ten closely related species with ellipsoid-ovoid basidia, and the genus type, Eichleriella incarnata, is placed to the synonyms of Eichleriella leucophaea. Eichleriella bactriana, Eichleriella desertorum and Eichleriella sicca are described as new to science. In addition, four species earlier treated as members of Exidiopsis or Heterochaete are combined to the genus. The genus name Heteroradulum (type Radulum kmetii) is introduced for seven species with large, obconical, stipitate basidia. Of them, Heteroradulum adnatum and Heteroradulum semis are described as new. Two new genera, Amphistereum (with two species, type Eichleriella schrenkii) and Sclerotrema (monotypic, type Exidiopsis griseobrunnea), are proposed; Hirneolina (monotypic, type H. hirneoloides) and Tremellochaete (with two species, type Exidia japonica) are restored as good genera. The type species of Heterochaete, H. andina, is congeneric with Exidiopsis (type E. effusa).
在本研究中，我们对具有平伏或杯状、持久担子果的木耳目进行了分类研究；基于形态学和DNA证据对属和种的概念进行了修订。恢复了Eichleriella属，包含十个具有椭圆形至卵形担子的近缘种，该属模式种Eichleriella incarnata被置于Eichleriella leucophaea的异名中。描述了Eichleriella bactriana、Eichleriella desertorum和Eichleriella sicca为新物种。此外，四个先前被视为Exidiopsis或Heterochaete成员的物种被归入该属。为七个具有大型、倒锥形、具柄担子的物种引入了属名Heteroradulum（模式种Radulum kmetii）。其中，Heteroradulum adnatum和Heteroradulum semis被描述为新物种。提出了两个新属，Amphistereum（含两个物种，模式种Eichleriella schrenkii）和Sclerotrema（单型，模式种Exidiopsis griseobrunnea）；恢复了Hirneolina（单型，模式种H. hirneoloides）和Tremellochaete（含两个物种，模式种Exidia japonica）为有效属。Heterochaete的模式种H. andina与Exidiopsis（模式种E. effusa）同属。
