The clade was formed by species mainly isolated from dung and soil and supported with a 98% bootstrap value in multilocus data analysis. In addition to Neogymnomyces, the generic types Auxarthronopsis bandhavgarhensis (ex-type culture: CBS 134524, from soil inside hollow tree, India), Canomyces reticulatus (ex-type culture: MCC 1486, from soil under a tree, India), Currahmyces indicus (ex-type culture: MCC 1548, from hen-populated soil, India) and Renispora flavissima (ex-type culture: CBS 708.79 from soil in barn housing Myotis velifer, USA) were placed in the clade. Based on the generic types of the genera, Clade 7 can be divided into two main groups: Group Neogymnomyces and Group Auxarthronopsis. Canomyces reticulatus, Auxarthronopsis stercicola (ex-type culture: CGMCC3.19639, from animal feces in karst Cave, China) and Auxarthronopsis pulverea (ex-type culture: CGMCC3.19312, from plant debris in karst Cave, China) clustered in the same group based on LSU and multilocus data analyses; however, Canomyces was in a different group in the ITS tree. The similarity of Auxarthronopsis pulverea and Canomyces reticulatus was 84% for ITS and 98% for LSU loci. Similarly, ITS identity for Auxarthronopsis stercicola and Canomyces reticulatus was found to be 85%, while the LSU identity was 98%. Morphological differences between these species were recorded in previous studies (Zhang et al. 2021; Sharma and Shouche 2021). The ITS similarity of Auxarthronopsis stercicola and A. pulverea was 97%, while the LSU similarity between these two species and the type species A. bandhavgarhensis was 85% and 86%, respectively. These results support that A. stercicola and A. pulverea belong to the same genus, but they should be excluded from Auxarthronopsis. Additionally, Amauroascus purpureus (ex-type culture: UAMH 8294, from cultivated soil, Japan), Amauroascus volatilispatellus (ex-type culture: CBS 249.72, from clay soil, USA) and Nannizziopsis mirabilis (ex-type culture: UAMH 7712, from forest soil, USA) in Clade 7 also need nomenclatural revision since they are remote from their generic types Amauroascus niger (ex-type culture: CBS 114.61, from soil, USA) and Nannizziopsis vriesii (ex-type culture: CBS 407.71, from lizard skin and lung, The Netherlands).
Another keratinophilic fungus, Chlamydosauromyces punctatus (ex-type culture: UAMH 9990, from skin of lizard, USA), is also placed in Clade 7 along with Neogymnomyces species based on ITS phylogeny. With the original description of C. punctatus, Neogymnomyces species were not included in the analyses since the molecular data were not available at that time (Sigler et al. 2002b). In the present study, ITS similarity between C. punctatus and N. demonbreunii was found to be 94%. Both genera are keratinophilic and have gymnothecial ascomata; however, their ascospore and culture morphologies are different (Sigler et al. 2002b; Doveri et al. 2012).
