Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1
Classification: Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Etymology: Refers to its phylogenetic relationship with the genus Tainosphaeria.
Diagnosis: Setae absent. Conidiophores simple, cylindrical, extended percurrently; Conidiogenous cells terminal, monophialidic, verruculose, collarettes inconspicuous. Conidia globose to subglobose, thick and roughwalled, hyaline, aseptate, bearing 2–3 setulae. Similar to Codinaeella and Tainosphaeria, but differs in producing rough-walled monophialidic conidiogenous cell with inconspicuous collarette, and globose to subglobose, roughand thick-walled conidia bearing 2-3 setulae.
Colonies effuse, hairy, dark brown. Mycelium partly superficial and partly immersed, composed of pale brown to brown, branched and septate hyphae. Teleomorph: Unknown. Anamorph: Conidiophores macronematous, simple, erect, straight or slightly flexuous, dark brown to reddish brown, 4–6-septate, smooth-walled in the lower part, becoming strongly verruculose in the upper part and with irregularly arranged striate, thick-walled, with a swollen basal cell, extending percurrently through collarette, terminated in a conidiogenous cell, . Conidiogenous cells integrated, terminal, monophialidic, cylindrical, thick- and rough-walled, dark brown, apex pale brown, with a narrow sporulating locus, collarette indistinct. Conidia holoblastic, acrogenous, solitary, globose to subglobose, hyaline, rough- and thick-walled, with 2–3 slender appendages, accumulating in a head at the tips of the conidiogenous cells.
Geographical distribution: China
Notes: Morphologically Neotainosphaeria is similar to some species of Codinaeella and Tainosphaeria with globose to ellipsoidal conidia, but differs in producing the rough-walled, monophialidic conidiogenous cell with inconspicuous collarette, and globose to subglobose, rough- and thick-walled conidia bearing 2-3 setulae. It also resembles Calceispora and Bahusutrabeeja s. lat, but can be distinguished from them by monophialidic conidiogenous cells bearing narrower sporulating loci with inconspicuous collarette, rough- and thick-walled conidia with both lateral setulae (Matsushima 1975; Subramanian and Bhat 1977; Seifert et al. 2011).
