Pseudoneottiospora
Pseudoneottiospora Faurel & Schotter, Revue Mycol., Paris 29(4): 278 (1965) [1964]
Faces of fungi number: FoF 07540
Ascomycota, genera incertae sedis
Coprophilous on dung of sheep and rabbit (Nag Raj 1993). Sexual morph: undetermined. Asexual morph: Conidiomata dark brown to black, pycnidial, scattered to gregarious, immersed to semi-immersed, globose to subglobose, ovoid, pyriform or irregular in section view, unilocular, glabrous, ostiolate. Ostiole circular or oval, centrally located. Conidiomatal wall composed of thick-walled, dark brown to hyaline cells of textura angularis to textura globulosa or textura prismatica in basal and lateral part, becoming darker at the ostiolar region. Conidiophores arising from inner wall layer of conidiomata, hyaline, cylindrical to subcylindrical, branched, septate, smooth-walled, invested in mucus. Conidiogenous cells hyaline, enteroblastic, annellidic, lageniform to cylindrical, integrated or discrete, indeterminate, smooth-walled. Conidia hyaline, cylindrical to fusiform, with narrow truncate base, straight or bent, 1–3-septate, uneven, smooth-walled, guttulate, bearing apical appendages; appendages 2–4, filiform, tubular, flexuous, unbranched, attenuated toward apex (Morgan-Jones 1977, Nag Raj 1993).
Type species: Pseudoneottiospora cunicularia Faurel & Schotter, Revue Mycol., Paris 29(4): 279 (1965) [1964]
Notes: Pseudoneottiospora is a coprophilous genus with conidial appendages, which led to a comparison with Dimastigosporium, Monodia, Pirispora, Pullospora and Quezeua. However, Dimastigosporium was separated from other genera by its stromatic, cupulate, superficial, setose conidiomata. Monodia is distinguished by its pycnidial, setose conidiomata. The type specimens of Pirispora and Quezeua do not exist in any herbaria (Nag Raj 1993). Quezeua has black pycnidial conidiomata without basal tissue but anchored to the substrate by brown mycelium, and hyaline ellipsoid-fusiform, 1-septate conidia with three appendages at each end (Nag Raj 1993). Pirispora differs from these genera by its hyaline, cuneiform, aseptate conidia with a tubular basal appendage, separated from the conidium body by a septum, and three similar, but divergent, appendages maintaining protoplasmic continuity with the conidium body (Nag Raj 1993). Pseudoneottiospora differs from Pullospora by its cylindrical to fusiform, 1–3-septate, uneven conidia with 2–4, tubular, apical appendages.
The type specimen of Pseudoneottiospora cunicularia was destroyed during the Algerian uprising (Morgan-Jones 1977), therefore, the description is based on P. coprophila and P. patouillardii Nag Raj. Pseudoneottiospora coprophila was initially proposed by Breton and Faurel (1967) on the basis of Neottiospora coprophila Speg., but this proposal was not validly published. Nag Raj (1993) considered P. coprophila is valid name and provided a detailed description and illustration. However, the name of Pseudoneottiospora coprophila was not listed in Index Fungorum and MycoBank. Thus we need to include this name to Index Fungorum and MycoBank following Nag Raj’s (1993) comments. No molecular sequence data is available for this genus.
Distribution: Italy, Tunisia (Nag Raj 1993).
