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

Saprobic on deadwood. Sexual state: Ascomata superficial, borneonathin, darkbrown subiculum, solitary or scattered, globose to subglobose, reddish-brown to dark brown, with brown to dark brown, septate, setae, mostly at the apex. Peridium comprising 3–4 layers of red brown to dark brown cells of textura angularis. Hamathecium comprising filiform, hyaline pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, cylindrical to clavate, apically rounded, short pedicellate, with long apical region with amorphous contents. Ascospores 2–3-seriate,fusiform to clavate, broader above, straight to slightly curved,5-septate, constricted at septum, hyaline, smooth-walled. Asexual state: hyphomycetous, helicosporous. Micronematous conidia-like structures, develop directly from hyphae in culture (from Boonmee et al. 2011).

Notes: Thaxteriellopsis is a strongly-supported genus in the phylogenetic analysis with 100% BS and 1.00 PP (Clade B, Fig. 2). The type species, T. lignicola, is associated with a moorella-like asexual morph (Subramanian and Sekar 1982). Boonmee et al. (2011) found that Thaxteriellopsis lignicola produced micronematous, brown, helicosporous, septate, conidia-like structures directly on the hyphae in culture. For an account of this genus, see Boonmee et al. (2011).
