Neopaucispora

Neopaucispora Wanas., Gafforov & K.D. Hyde, in Wanasinghe et al., Fungal Diversity 89: [65] (2018).

Index Fungorum number: IF 554146; Facesoffungi number: FoF 03986, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic on dead twigs in terrestrial habitats. Sexual morph: Ascomata scattered to gregarious, immersed or semi erumpent, coriaceous, black, globose to subglobose, ostiolate. Ostiole slit-like, central, with a crest-like papilla, with an irregular, pore-like opening. Peridium wider at the apex, and thinner at the base, composed of several layers with brown to black cells of textura angularis, cells towards the inside lighter and at the outside, darker, sometimes fusing and indistinguishable from the host tissues. Hamathecium comprising numerous, filamentous, branched septate, pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical-clavate, with a long pedicel, apically rounded with an ocular chamber. Ascospores overlapping uni- to biseriate, hyaline to dark brown, middle two cells mostly brown, ellipsoidal to fusiform, 1–3-septate, constricted at the septa, mostly constricted at middle septum, prominently guttulate, lacking a mucilaginous sheath. Asexual morph: Unknown (adapted from Wanasinghe et al. 2018).

Type species: Neopaucispora rosae-ecae Wanas., Gafforov & K.D. Hyde

Notes: Neopaucispora is characterised by immersed or semi-erumpent, coriaceous, globose to subglobose ascomata, cylindrical-clavate asci, with a long pedicel, and ellipsoidal to fusiform ascospores. Neopaucispora differs from Paucispora in having 3-septate, fusiform, hyaline to reddish-brown ascospores with brown central cells prominently guttulate. Neopaucispora is morphologically and phylogenetically a well-supported genus in Lophiostomataceae. Molecular markers available for Neopaucispora includes LSU, SSU, ITS and TEF-1.
