黑木耳目包含了具有不同担子和菌丝体的种类。从形态学和系统发育的角度，我们进行了分类研究Heteroradulum，最近验证的属内木耳目。Grammatus属被合并到Heteroradulum，因此其属型G. grammatus与Heteroradulum合并，G.semis被重新接受为Heteroradulum的成员。Heteroradulumaustraliense是根据三个澳大利亚标本新描述的。云南异齿龙被排除在本属之外，其属级分类地位尚不确定。因此，Heteroradulum的界限被重新界定，该属的概念被调整为包括irpicoid到poroid菌丝柄和具有夹子连接或简单隔膜的菌丝系统。本文提供了一个已被公认的九种异齿象的检索表。
Auriculariales accommodates species with diverse basidiomes and hymenophores. From morphological and phylogenetic perspectives, we perform a taxonomic study on Heteroradulum, a recently validated genus within the Auriculariales. The genus Grammatus is merged into Heteroradulum, and thus its generic type G.labyrinthinus is combined with Heteroradulum and G.semis is reaccepted as a member of Heteroradulum. Heteroradulumaustraliense is newly described on the basis of three Australian specimens. Heteroradulumyunnanense is excluded from this genus and its taxonomic position at the generic level is considered uncertain. Accordingly, the circumscription of Heteroradulum is re-delimited and the concept of this genus is adjusted by including irpicoid to poroid hymenophores and a hyphal system with clamp connections or simple septa. A key to all nine accepted species of Heteroradulum is presented.
