Neovaginatispora A. Hashim., K. Hiray. & Kaz. Tanaka
Index Fungorum number: IF 823147
Saprobic on dead herbaceous twigs and submerged wood. Sexual morph: Ascomata solitary, semi-immersed to erumpent, black, subglobose, coriaceous, ostiolate. Ostiole rounded or slit-like, central, with a pore-like opening. Peridium uneven in width, thinner at the base, two-layered, outer layer fusing with the host cells, inner layer comprising hyaline cells of textura angularis. Pseudoparaphyses numerous, cellular, hypha-like, septate. Asci 8-spored, bitunicate, fissitunicate, cylindric-clavate, with a short, bulbous pedicel, with an indistinct ocular chamber. Ascospores uni- to bi- seriate, fusiform with acute ends, septate, constricted at the septum, hyaline, smooth-walled, with globose appendages at both ends (Hashimoto et al. 2018; Bao et al. 2019). Asexual morph: Undetermined.
Type species: Neovaginatispora fuckelii (Sacc.) A. Hashim., K. Hiray. & Kaz. Tanaka
Notes: Neovaginatispora was proposed for Vaginatispora fuckelii (Sacc.) Thambug. et al. due to its thinner (up to 25 μm thick) and uniformly thick peridium (Hashimoto et al. 2018). However, the freshwater collection of Neovaginatispora fuckelii found by Bao et al. (2019) has thicker peridium (up to 40 μm thick) which is thinner at the base. The specimen HHUF 27325 examined by Thambugala et al. (2015) also showed the uneven peridium width. Phylogenetic analyses based on four strains of N. fuckelii guaranteed Neovaginatispora as a distinct genus (Hashimoto et al. 2018; Bao et al. 2019; Dong et al. 2020).
