Classification: Chaetomiaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Isolated from rice field soil. Sexual morph: Mycelium white, superficial, effuse. Ascomata cleistothecial, solitary or gregarious, globose to subglobose, dark brown to black, covered in hyaline hairs. Peridium composed of brown to hyaline cells of textura angularis. Asci 3–8-spored, unitunicate, obpyriform to oval, evanescent. Ascospores multi-seriate, stellate to irregular with up to 9 short protuberances when mature, aseptate, pale greenish brown to brown, with a germ pore on one protuberance, guttulate. Asexual morph: Undetermined (adapted from Ito and Nakagiri 1994).
Notes: The monotypic Stellatospora typified by S. terricola has stellate ascospores and was initially placed in Sordariaceae (Ito and Nakagiri 1994). Subsequently, the ex-type strain (CBS 811.95) is available (Wang et al. 2019; Vu et al. 2019), and nests in Chaetomiaceae (Wang et al. 2019; this study, 100%ML/1.00PP). Therefore, this genus belongs in Chaetomiaceae based on phylogenetic analysis.
Type species: Stellatospora terricola Tad. Ito & Nakagiri, Mycoscience 35(4): 413 (1994).
Other accepted species: Species Fungorum – search Stellatospora.
