sect. is characterized by the production of small to medium-sized basidiomata, high species diversity (including several cryptic taxa), and occurrence in a large variety of habitats. A new species to science, i.e. , is formally described by adopting an integrative approach based on morphological features, molecular criteria, and habitat characteristics. The multilocus phylogenetic analysis performed through the use of the internal transcribed spacer (ITS), the partial nuc 28S rDNA (28S), and the translation elongation factor 1-alpha () gene clearly demonstrates that is a sister species to and . In addition, exhibits distinct morphological features, including a predominantly white, smooth pileus with occasional tinges of gray, orange, violet, or yellowish colors lacking appressed scales and a single, solid rhizomorph at the stipe base. Furthermore, the presence of another 12 species of the . sect. was assessed in Greece, six of which constitute first national records, i.e. , and . The most notable morphological features of these six species are presented, and their distribution in Mediterranean Europe is discussed.
该组的特征是产生中小型担子果、物种多样性高（包括几个隐存类群），并出现在多种生境中。通过采用基于形态特征、分子标准和生境特征的综合方法，正式描述了一个科学新物种，即 。通过使用内部转录间隔区（ITS）、部分核28S rDNA（28S）和翻译延伸因子1-α（ ）基因进行的多位点系统发育分析清楚地表明， 是 和 的姐妹物种。此外， 具有独特的形态特征，包括主要为白色、光滑的菌盖，偶尔带有灰色、橙色、紫色或淡黄色色调，没有紧贴的鳞片，以及在菌柄基部有单个坚实的菌索。此外，还评估了希腊 的另外12个物种，其中6个是该国首次记录，即 、 和 。介绍了这6个物种最显著的形态特征，并讨论了它们在地中海欧洲的分布。
