Among ancestral fungi in Chaetothyriales, several groups have a life style in association with tropical ants, either in domatia or in carton-nests. In the present study, two strains collected from ant carton in Thailand and Malaysia were found to represent hitherto undescribed species. Morphological, physiological, phylogenetic data and basic genome information are provided for their classification. Because of the relatively large phylogenetic distances with known species confirmed by overall genome data, large subunit (LSU) and Internal Transcribed Spacer (ITS) ribosomal DNA sequences were sufficient for taxonomic circumscription of the species. The analyzed strains clustered with high statistical support as a clade in the family Trichomeriaceae. Morphologically they were rather similar, lacking sporulation in vitro. In conclusion, Incumbomyces delicatus and Incumbomyces lentus were described as new species based on morphological, physiological and phylogenetic analysis.
在 chaetothyriales 的祖先真菌中，有几个群体与热带蚂蚁有关联，要么在巢室中，要么在纸盒巢中。在本研究中，从泰国和马来西亚的蚁巢中收集到的两个菌株被发现代表了迄今未描述的物种。为了对其进行分类，提供了形态学、生理学、系统发育学数据和基本基因组信息。由于通过全基因组数据确认的与已知种的相对较大的系统发育距离，大亚基（LSU）和内部转录间隔区（ITS）核糖体 DNA 序列足以对物种进行分类。分析的菌株与 Trichomeriaceae 科的一个分支聚类，具有很高的统计支持。从形态上看，它们非常相似，在体外缺乏孢子形成。总之，根据形态学、生理学和系统发育分析，Incumbomyces delicatus 和 Incumbomyces lentus 被描述为新种。
