Fibrodontia 是木材栖息真菌的一个属，迄今为止由四个物种组成，其中包括 F. gossypina 作为属类型。对中国的两个新种 Fibrodontia austrosinensis 和 F. subalba 进行了描述和说明。来自中国西南部的Fibrodontia austrosinensis 的特征是具有大量小针孔的巨齿状至齿状子实体，具有分散、光滑的骨架菌丝和椭圆形担子孢子（尺寸为4.2-5.2 × 3.5-4.5 μm）的二分形菌丝系统。来自中国西北部西天山的 Fibrodontia subalba 的特征是具有齿状到 Hydn 状的膜梗、二分形菌丝系统和尺寸为 3.7-4.4 × 2.8-3.4 μm 的椭圆形担子孢子。从 nuc rDNA ITS1-5.8S-ITS2 (ITS) 和 nuc 28S rDNA (28S) 的 D1-D2 结构域以及 ITS、28S、翻译延伸因子 (tef1α) 和 RNA 聚合酶 II 第二大亚基 (rpb2) 的数据集推断出的系统发育支持 Fibrodontia 是 Trechisporales 中的单系属，而 F. austrosinensis 和 F. subalba 作为 Fibrodontia 内的独立谱系。多速率泊松树过程、自动条形码间隙发现和基于Fibrodontia ITS序列的遗传距离方法也支持F. austrosinensis和F. subalba作为不同的物种。简要讨论了最近从 Cystidiodendron 转移而来的 F. fimbriata 的分类地位。提供了所有六种已知纤维齿菌属的钥匙。
Fibrodontia is a genus of wood-inhabiting fungi consisting of four species so far, including F. gossypina as generic type. Two new species, Fibrodontia austrosinensis and F. subalba, are described and illustrated from China. Fibrodontia austrosinensis from southwestern China is characterized by a grandinioid to odontioid hymenophore with numerous small aculei, a dimitic hyphal system with scattered, smooth skeletal hyphae and ellipsoid basidiospores measuring 4.2–5.2 × 3.5–4.5 μm. Fibrodontia subalba from the West Tianshan Mountain in northwestern China is distinguished by an odontioid to hydnoid hymenophore, a dimitic hyphal system, and ellipsoid basidiospores measuring 3.7–4.4 × 2.8–3.4 μm. The phylogenies inferred from the data set of nuc rDNA ITS1-5.8S-ITS2 (ITS) and D1–D2 domains of nuc 28S rDNA (28S), and that of ITS, 28S, translation elongation factor (tef1α), and RNA polymerase II second largest subunit (rpb2) supported Fibrodontia as a monophyletic genus in the Trechisporales, and F. austrosinensis and F. subalba as separate lineages within Fibrodontia. Multi-rate Poisson Tree Processes, Automatic Barcode Gap Discovery and genetic distance methods based on ITS sequences of Fibrodontia also supported F. austrosinensis and F. subalba as distinct species. The taxonomic status of F. fimbriata that was recently transferred from Cystidiodendron, is briefly discussed. A key to all six known species of Fibrodontia is provided.
