Classification: Sordariaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Isolated from soil. Sexual morph: Ascomata cleistothecial, solitary or gregarious, superficial to immersed in the medium, globose to subglobose, membranaceous, brown to black, glabrous. Peridium composed of membranaceous, hyaline to subhayline cells of textura angularis. Asci 4-spored, unitunicate, clavate to cylindrical, short pedicellate, apex rounded, evanescent. Ascospores hyaline, becoming dark brown, oval to citriform,1–2-apiculate, aseptate, with a germ pore at one or each end. Asexual morph: Undetermined (adapted from Lodhi and Mirza 1962; Wang et al. 2019).
Notes: The monotypic genus Boothiella was introduced as a member of Eurotiales and its ascospores are similar to Thielavia (Lodhi and Mirza 1962). Kirk et al. (2008) transferred Boothiella to Sordariaceae and Maharachchikumbura et al. (2015, 2016) placed this genus in Chaetomiaceae. Vu et al. (2019) and Wang et al. (2019) analyzed sequence data from isolates CBS 334.67 (ex-type) and CBS 887.97, and showed that B. tetraspora nests in Sordariaceae. In the present study, Boothiella strains form a clade in Sordariaceae (100%ML/1.00PP).
Type species: Boothiella tetraspora Lodhi & J.H. Mirza, Mycologia 54(2): 217 (1962).
