, belonging to , , comprises most polypores and corticioid fungi and, also, a few agarics. The latest taxonomic framework accepts 14 families in this order. When further exploring species diversity of , two corticioid specimens collected from China producing cystidia with large umbrella-shaped crystalline heads attracted our attention. This kind of cystidia was reported only in three unsequenced species, viz. , and , which were accepted in , . The current multilocus-based phylogeny supports that the two Chinese specimens formed an independent lineage from as well as the additional 13 families and all sampled genera in . Therefore, a monotypic family, is newly described with the new genus as the type genus to represent this lineage. The two Chinese specimens are newly described as , which differs from , and in a combination of a smooth to grandinioid hymenophoral surface, not flattened, broadly ellipsoid basidiospores with a tiny apiculus, and growth on angiosperm wood. Due to the presence of the unique cystidia, the three species of , even though they lack available molecular sequences, are transferred to as , and . Hereafter, all known species with large umbrella-shaped crystalline-headed cystidia are in a single genus. In summary, the current study provides a supplement to the latest taxonomic framework of and will help to further explore species diversity and the evolution of this fungal order.
属于，包含大多数多孔菌和革菌，也包括一些伞菌。最新的分类框架在这个目下接受14个科。在进一步探索物种多样性时，从中国采集的两个产生带有大伞形结晶头部囊状体的革菌标本引起了我们的注意。这种囊状体仅在三个未测序的物种中被报道过，即，和，它们在，中被接受。当前基于多基因座的系统发育支持这两个中国标本与以及另外13个科和中所有采样属形成一个独立的谱系。因此，一个新描述的单型科，以新属作为模式属来代表这个谱系。这两个中国标本被新描述为，它在平滑至颗粒状的子实层表面、不扁平、具微小尖突的宽椭圆形担孢子以及在被子植物木材上生长等特征组合上与，和不同。由于独特囊状体的存在，这三个物种，尽管它们缺乏可用的分子序列，被转移到作为，和。此后，所有已知的具有大伞形结晶头部囊状体的物种都在一个单一的属中。总之，当前的研究为的最新分类框架提供了补充，并将有助于进一步探索该真菌目的物种多样性和进化。
