Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1

Classification: Sordariaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Isolated from soil. Sexual morph: Mycelium composed of hyaline to brown, branched hyphae. Ascomata perithecial or cleistothecial, gregarious or scattered, superficial to immersed, yellowish to brown or black, sometimes translucent, pyriform to subglobose, ostiolate, surrounded by hyaline, septate hyphae or sinuose, brown, septate setae. Peridium membranaceous, comprising brown to hyaline cells of textura angularis or textura globulosa. Asci 8-spored, unitunicate, cylindrical to clavate, short pedicellate, apex rounded, with J- apical ring, evanescent. Ascospores uni- or bi- seriate, hyaline when young becoming dark brown or black, oval to ellipsoidal, aseptate, verrucose to tuberculate, with a germ pore at each end. Asexual morph: Undetermined (adapted from Udagawa 1980; García et al. 2004).

Notes: García et al. (2004) introduced Pseudoneurospora for Gelasinospora amorphoporcata based on phylogenetic analysis. They mentioned that this genus has ascospores with a strongly verrucose to tuberculate irregular pattern on the surface (Udagawa 1980; García et al. 2004). Subsequently, a second species, P. canariensis, was introduced by Crous et al. (2014) having similar ascospore morphology and molecular data. In this study, an invalid name ‘Copromyces octosporus’ (CBS 386.78) is sister to P. canariensis (see notes for Copromyces). Pseudoneurospora species clustered with 92%ML/1.00PP support and basal to Sordaria clade II in Sordariaceae (97%ML/1.00PP).

Type species: Pseudoneurospora amorphoporcata (Udagawa) Dania García et al., Mycological Research 108 (10): 1139 (2004).

Other accepted species: Species Fungorum – search Pseudoneurospora.
