Index Fungorum, Facesoffungi, MycoBank, GenBank.
Classification: Incertae sedis, Incertae sedis, Incertae sedis, Incertae sedis, Pezizomycotina, Ascomycota, Fungi
Saprobic on plants, such as Carex acutiformis, C. appropinquata, C. elata, C. pendula, C. riparia (Cyperaceae), Iris pseudacorus (Iridaceae), Panicum maximum (Poaceae) and Typha latifolia (Typhaceae) (Sutton 1980, Nag Raj 1993, this study). Sexual morph: undetermined. Asexual morph: Conidiomata olivaceous green to black, pycnidial, scattered to gregarious or confluent, deeply immersed, ellipsoidal to globose, unilocular, glabrous, thick-walled, ostiole absent, but with a circular operculum, dehiscence by forming two lines between the operculum and upper conidiomatal wall. Conidiomatal wall composed of thick-walled, olivaceous green to hyaline cells of textura angularis to textura prismatica. Conidiophores arising all around cavity of conidiomata, hyaline, cylindrical, branched, septate, smooth-walled. Conidiogenous cells hyaline, enteroblastic, phialidic, clavate to subcylindrical, discrete or integrated, indeterminate, with periclinal thickenings at collarette zone, smooth-walled. Conidia hyaline, fusiform to ellipsoidal, straight or slightly curved, aseptate, smooth-walled, guttulate, bearing an appendage at base, initially funnel-shaped but ultimately splitting into tentacular strands.
Notes: The generic name Neottiospora was introduced by Desmazièrcs (1843) with N. caricum Desm. as the type species, collected from Carex sp. (Cyperaceae) in France. Berkeley and Broome (1850) synonymized Sphaeria caricina Desm. with N. caricum. von Höhnel (1924) re-examined both type materials and concluded that the species are conspecific and named it as Neottiospora caricina (Desm.) Höhn. Höhnel’s finding was confirmed by Cunnell (1957) and this name was adopted in later studies (Cunnell 1957, Pirozynski and Shoemaker 1971, Nag Raj 1973, 1993, Sutton 1980).
Type species: Neottiospora caricina (Desm.) Höhn., in Weese, Mitt. bot. Inst. tech. Hochsch. Wien 1(3): 78 (1924).
Other accepted species: Species Fungorum – search Neottiospora.
