A taxonomic treatment of vinaceous and reddish species of Tubaria (Agaricales) is presented based on morphology and nucleotide sequences. Accessions from western North America, Europe, Central America, the Caribbean and Australia are compared. Phylogenetic analysis of the 25S rRNA gene and internal transcribed spacer (ITS) regions demonstrates that Tubaria is not monophyletic. However the autonomy of six brown-spored, saprotrophic species-Naucoria vinicolor, Pholiota serrulata, Phaeomarasmius confragosus, Pholiota punicea, Tubaria rufofulva and T. bispora sp. nov.-is affirmed. All six species form a strongly supported monophyletic group that we label section Confragosae in the genus Tubaria. This section is related to T. dispersa, T. albostipitata and numerous representatives of the T. furfuracea complex. Tubaria minima is related to other lineages of dark-spored Agaricales. Taxonomic descriptions, illustrations and a key to confirmed species of section Confragosae are provided. Four new combinations are proposed, and one new species, T. bispora, is described as new from Costa Rica and Martinique. A lectotype is designated for Pholiota serrulata.
基于形态学和核苷酸序列,对酒红色和带红色的小皮伞属(伞菌目)物种进行了分类处理。比较了来自北美西部、欧洲、中美洲、加勒比地区和澳大利亚的样本。对25S rRNA基因和内部转录间隔区(ITS)区域的系统发育分析表明,小皮伞属并非单系类群。然而,六个棕色孢子、腐生的物种——酒红色瑙氏伞、细锯齿鳞伞、破碎褐小皮伞、橙黄鳞伞、红褐小皮伞和双孢小皮伞新种——的独立性得到了确认。所有这六个物种形成了一个得到有力支持的单系类群,我们将其在小皮伞属中标记为破碎褐小皮伞组。该组与分散小皮伞、白柄小皮伞以及糠皮小皮伞复合体的众多代表物种相关。极小小皮伞与深色孢子伞菌目的其他谱系有关。提供了破碎褐小皮伞组已确认物种的分类描述、插图和检索表。提出了四个新组合,并描述了一个新物种——双孢小皮伞,它来自哥斯达黎加和马提尼克岛。为细锯齿鳞伞指定了一个选模式。
