The phylogeny of the poroid and hydnoid genera Antrodiella, Junghuhnia, and Steccherinum (Polyporales, Basidiomycota) was studied utilizing sequences of the gene regions ITS, nLSU, mtSSU, atp6, rpb2, and tef1. Altogether 148 taxa, represented by 549 sequences, were included in analyses. Results show that most species of these genera form a well supported clade in the Polyporales, called Steccherinaceae, along with 12 other hydnoid and poroid genera. Within the Steccherinaceae, generic concepts need to be revised: no fewer than 15 new genera are needed to accommodate existing and new species. At least 16 transitions have taken place between poroid and hydnoid hymenophore types within the Steccherinaceae, and similar plasticity can be seen in microscopic characters. Nevertheless, natural genera revealed in the analysis can mostly be characterized morphologically and, with few exceptions, poroid and hydnoid species belong to separate genera. The genus Steccherinum is shown to contain both hydnoid and poroid species. Species of the former Antrodiella belong to at least 10 genera within the Steccherinaceae. © The Willi Hennig Society 2011.
利用ITS、nLSU、mtSSU、atp6、rpb2和tef1基因区域的序列，对多孔菌属和齿菌属的小孔菌属（Antrodiella）、绒盖多孔菌属（Junghuhnia）和干酪菌属（Steccherinum）（多孔菌目，担子菌门）的系统发育进行了研究。分析共纳入了由549个序列代表的148个分类单元。结果表明，这些属的大多数物种在多孔菌目中形成了一个得到充分支持的分支，称为干酪菌科，该分支还包括其他12个齿菌属和多孔菌属。在干酪菌科内，属的概念需要修订：至少需要15个新属来容纳现有的和新的物种。在干酪菌科内，多孔菌和齿菌子实层体类型之间至少发生了16次转变，在微观特征上也可以看到类似的可塑性。然而，分析中揭示的自然属大多可以通过形态学来表征，除少数例外，多孔菌和齿菌物种属于不同的属。干酪菌属被证明同时包含齿菌和多孔菌物种。原小孔菌属的物种至少属于干酪菌科内的10个属。©威利·亨尼希学会2011年。
