与Phanerochaete s.l具有亲缘关系的两个新属。，分别为Hydnophanerochaete和Odontoefibula。水龙的属型为齿隐毛虫总科。Odontoefibla是在一个新种的基础上建立的：O.orientalis(属型)。两属担子果具齿状处女膜表面，单隔开的生殖菌丝，无孢囊器，棍棒状担子和椭圆形担孢子，光滑，薄壁，淀粉样，非糊精类和嗜无色性。Hydnophanerochaete的另一个特征是在下茎中具有致密的质地，具有厚壁的生殖菌丝和准结合的菌丝。当用KOH处理时，齿状腓骨具有致密的细基质地和薄壁到略厚的菌丝，并且进一步有担子的暗红色反应。基于ITS+nuc 28S+rpb1+rpb2+tef1序列的多标记系统发育分析表明，Hydnophanerochaete和Odontoefibula分别隶属于Phanerochaetaceae的Meruliaceae和Donkia支系。根据形态和分子证据，裸毛亚齿总科(Phanerochaetessubdontoidae)是齿假单胞菌总科的同义词。
Two new genera with phylogenetic affinities to Phanerochaete s.l. are presented, namely Hydnophanerochaete and Odontoefibula. The generic type of Hydnophanerochaete is Phanerochaeteodontoidea. Odontoefibula is established based on a new species: O.orientalis (generic type). Both genera have effused basidiocarps with odontioid hymenial surface, simple-septate generative hyphae, cystidia lacking, clavate basidia and ellipsoid basidiospores that are smooth, thin-walled, inamyloid, non-dextrinoid and acyanophilous. Hydnophanerochaete is additionally characterised by a compact texture in the subiculum with thick-walled generative hyphae and quasi-binding hyphae. Odontoefibula has a dense texture of subiculum with thin- to slightly thick-walled hyphae and further a dark reddish reaction of basidiocarps when treated with KOH. Multi-marker phylogenetic analyses based on sequences, inferred from the ITS+nuc 28S+rpb1+rpb2+tef1 dataset, indicate that Hydnophanerochaete and Odontoefibula are placed in the Meruliaceae and Donkia clades of Phanerochaetaceae, respectively. Phanerochaetesubodontoidea is a synonym of P.odontoidea, according to morphological and molecular evidence.
