A new basidiomycete genus, Rhizochaete (Phanerochaetaceae, Polyporales), is described. Rhizochaete is characterized by a smooth to tuberculate, pellicular hymenophore and hyphal cords that turn red or violet in potassium hydroxide, monomitic hyphal system of simple or nodose septate hyphae, cystidia, and small, cylindrical to subglobose basidiospores. It morphologically is most similar to Phanerochaete. Analyses of nuclear ribosomal and internal-transcribed spacer region sequence data support a close relationship between Rhizochaete and Phanerochaete. The new taxon R. brunnea, from southern Argentina, is described and illustrated. In addition, the new combinations R. americana, R. borneensis, R. filamentosa, R. fouquieriae and R. radicata are proposed. A key to the species of Rhizochaete is provided.
一个新的担子菌属，Rhizochaete（Phanerochaetaceae，Polyporales），被描述。Rhizochaete 的特征是具有光滑到多结节的、膜状的子实层体和菌丝索，在氢氧化钾中变红或变紫，单型的菌丝系统由简单或有节结的分隔菌丝组成，有囊状体和小的、圆柱形到近球形的担孢子。它在形态上与 Phanerochaete 最为相似。核核糖体和内部转录间隔区序列数据分析支持 Rhizochaete 和 Phanerochaete 之间的密切关系。来自阿根廷南部的新分类群 R. brunnea 被描述并图示。此外，还提出了新的组合 R. americana、R. borneensis、R. filamentosa、R. fouquieriae 和 R. radicata。提供了 Rhizochaete 种的一个关键。
