We studied the taxonomy of , and morphologically similar Holarctic species in the /romellii clade of section , using morphological and molecular data (nrITS, ). is lectotypified and epitypified and accepted as an exclusively Eurasian species. and are considered synonyms of . is accepted as a related, but separate, North American species. Five species in the /romellii clade are described as new to science: two from North America ( and ), one from Asia (), one from Europe (), and one widely distributed across the Holarctic region (). Basidioma size, pileus color, lamellae color, basidiospore size, hymenial cystidia shape and size, habitat and geographical distribution help separate the species described here, but in some instances only molecular data allows for confident identification. The current status of , , var. , , and is discussed.
我们使用形态学和分子数据（nrITS）对 section 的 /romellii 分支中 以及形态相似的全北区物种进行了分类研究。 被选定模式和附加模式，并被认定为仅分布于欧亚大陆的物种。 和 被视为 的同义词。 被认定为一个相关但独立的北美物种。/romellii 分支中的五个物种被描述为科学新物种：两个来自北美（ 和 ），一个来自亚洲（），一个来自欧洲（），还有一个广泛分布于全北区（）。担子果大小、菌盖颜色、菌褶颜色、担孢子大小、子实层囊状体形状和大小、生境和地理分布有助于区分此处描述的物种，但在某些情况下，只有分子数据才能进行可靠鉴定。文中还讨论了 、 、 变种 、 、 的当前分类地位。
