MycoBank number: MB 5409; Index Fungorum number: IF 5409; Facesoffungi number: FoF 01866; – 1 morphological species (Lu et al. 2018b), 1 species with molecular data.

Type species: Thaxteriellopsis lignicola Sivan., Panwar & S.J. Kaur, Kavaka 4: 39 (1977) [1976].

Notes: Crane et al. (1998) transferred T. lignicola to Chaetosphaerulina. Boonmee et al. (2011) reexamined the holotype of T. lignicola (IMI 197065), designated an epitype (MFLU 10-0057), and retained Thaxteriellopsis as a distinct genus within Tubeufiaceae. Doilom et al. (2017) introduced an asexual record of T. lignicola based on phylogenetic evidence. Lu et al. (2018b) reported new records of T. lignicola with new morphological characteristics. Thaxteriellopsis is characterized by globose to subglobose ascomata are reddish brown to dark brown, collapsed when dry, and covered with brown to black setae, cylindrical asci with a long pedicel, and straight or slightly curved ascospores are fusiform to clavate with 5 septa. The conidia of Thaxteriellopsis are typical helicoma-like but conidiophores are distinct from Helicoma species (Boonmee et al. 2011; Doilom et al. 2017; Lu et al. 2018b).
