Species in the genus have a worldwide distribution and are isolated from various substrata and hosts, including soil, dung, freshwater, and fruits. However, their diversity from insects is still much too little explored. The aim of this study was to characterize three new species of : sp. nov., . sp. nov., and . sp. nov., discovered in Kunryang-ri, Cheongyang in the Chungnam Province of Korea, during an investigation of from cricket insects. The new species are described using morphological characters and molecular data including ITS and LSU rDNA regions. is characterized by the highly variable shape of its columellae, which are subglobose to oblong, obovoid, strawberry-shaped, and sometimes slightly or strongly constricted in the center. is characterized by the production of azygospores and growth at 40 °C. is characterized by the variable shape of its columellae, which are elongated-conical, obovoid, cylindrical ellipsoid, cylindrical, and production of abundant yeast-like cells on PDA, MEA, and SMA media. Based on the sequence analysis of two genetic markers, our phylogenic assessment strongly supported , . and . as new species. Detailed descriptions, illustrations, and phylogenetic trees are provided.
该属的物种分布于全球，可从各种基质和宿主中分离得到，包括土壤、粪便、淡水和水果。然而，它们在昆虫中的多样性仍有待深入探索。本研究的目的是对在韩国忠清南道清阳市昆良里调查蟋蟀昆虫时发现的三个新物种进行特征描述：新种 、新种 和新种 。利用形态特征和包括ITS和LSU rDNA区域在内的分子数据对新物种进行了描述。 的特征是其小柱形状高度可变，呈近球形至长方形、倒卵形、草莓形，有时在中心略微或强烈收缩。 的特征是产生单孢子并在40°C下生长。 的特征是其小柱形状可变，呈细长圆锥形、倒卵形、圆柱形椭圆形、圆柱形，并且在PDA、MEA和SMA培养基上产生大量酵母样细胞。基于两个遗传标记的序列分析，我们的系统发育评估有力地支持了 、 和 为新物种。文中提供了详细的描述、插图和系统发育树。
