At present, 25 species are accepted in and are distributed in Asia, Europe, North America, South America, Australia, and Africa. In this study, two new species, from Ecuador and from China, are described and illustrated based on morphological examination and phylogenetic analyses. is characterized by annual, resupinate basidiomata with pinkish buff to honey yellow hymenophore when dry, round to angular pores of 2-4 per mm, a dimitic hyphal structure with generative hyphae bearing clamp connections, hyphae at dissepiment edge usually with one or two simple septa, the presence of dendrohyphidia and cystidioles, and oblong to ellipsoid basidiospores measuring 14.9-17.9 × 6.9-8.8 µm. differs from other species in that it has a monomitic hyphal system and strongly dextrinoid basidiospores. The differences between the new species and morphologically similar and phylogenetically related species are discussed. In addition, an updated key to 27 species of is provided.
目前，被接受的有 25 个种，分布于亚洲、欧洲、北美洲、南美洲、澳大利亚和非洲。本研究基于形态学观察和系统发育分析，描述并图示了来自厄瓜多尔的两个新种， 和来自中国的 。 是一年生、反卷的担子果，干燥时菌盖表面呈浅粉棕色至蜂蜜黄色，具 2-4 毫米/毫米的圆形至角状孔，二体型的菌丝结构，生殖菌丝具锁状联合，分隔缘菌丝通常具 1 至 2 个简单的隔膜，具树状拟晶和囊状体，以及长椭圆形至椭圆形的担孢子，大小为 14.9-17.9×6.9-8.8µm。 与其他 种的不同之处在于它具有单体型的菌丝系统和强烈的淀粉质的担孢子。讨论了新种与形态相似和系统发育上相关的种之间的差异。此外，还提供了 27 种 的更新的鉴别特征。
