本文记述了担子菌一新属--根霉属。根毛菌的特征是光滑到具瘤，膜状膜柄和在氢氧化钾中变成红色或紫色的菌丝索，由单菌丝或节状隔开的菌丝组成的单体菌丝系统，囊状，小的圆柱状到近球形的担孢子。它在形态上与裸毛类最为相似。对不清楚的核糖体和内部转录间隔区序列数据的分析支持根毛虫和裸毛虫之间的密切关系。对产于阿根廷南部的新分类群R.brunnea进行了描述和图解。此外，还提出了美洲大麦、小米大麦、丝状大麦、黑大麦和根大麦的新组合。提供了根毛菌的种类检索表。
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 unclear 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.
