, a small and under-studied family of , includes mostly saprophytic taxa with varied basidiomes. In this study, we focus on wood-decay species with corticioid or stereoid basidiomes. Phylogenetic analyses of concatenated - sequences uncovered seven generic lineages of corticioid or stereoid fungi-, , , , , , and gen. nov. The genus is shown to be in the family, and two new species, and , are described from East Asia. Morphologically, . is characterized by resupinate basidiomes with smooth hymenophores, a dimitic hyphal system with clamped generative hyphae and micro-binding hyphae, cystidia with resinous-like or golden yellow contents, and ellipsoid basidiospores. is monotypic, differing from by a trimitic hyphal system of clamped generative, micro-binding, and brown, thick-walled skeletal-like hyphae, clavate to cylindrical cystidia with homogenous, colorless contents, and hyphidia. Descriptions and illustrations are provided for the new taxa and , and a key to corticioid or stereoid genera in is included.
，一个小型且研究不足的 科，主要包括具有多样担子果的腐生类群。在本研究中，我们聚焦于具有革菌状或多孔菌状担子果的木材腐朽物种。对串联的 序列进行系统发育分析，发现了革菌状或多孔菌状真菌的七个属系—— 、 、 、 、 、 以及新属 。已证明 属属于 科，并且从东亚描述了两个新物种，即 和 。在形态上， 。 的特征为平伏的担子果，其菌褶表面光滑，具有双核菌丝系统，包括具锁状联合的生殖菌丝和微联结菌丝，囊状体含有树脂状或金黄色内含物，以及椭圆形担孢子。 属为单型属，与 的不同之处在于其三核菌丝系统，包括具锁状联合的生殖菌丝、微联结菌丝以及褐色、厚壁的类骨架菌丝，棒状至圆柱形的囊状体含有均匀、无色的内含物，以及菌丝侧体。为新分类单元 和 提供了描述和图示，并包含了 科中革菌状或多孔菌状属的检索表。
