Boothiella tetraspora

Boothiella tetraspora Lodhi & J.H. Mirza, Mycologia 54(2): 217 (1962)

Facesofungi number: FoF 10130; Fig. X  

Isolated from soil. Sexual morph: Ascomata cleistothecial, solitary or gregarious, superfcial 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. 2019a, b). Known hosts and distribution: On soil in Pakistan (type locality) (Lodhi and Mirza 1962); on sand in Spain (Wang et al. 2019a, b).

Notes: Boothiella tetraspora is similar to Thielavia, except for its translucent ascomata (Lodhi and Mirza 1962). Wang et al. (2019a, b) proposed that this species resembles Hyalosphaerella fragilis and Pseudothielavia subhyaloderma (Chaetomiaceae), but the former has 4-spored and the latter two have 8-spored asci. However, B. tetraspora nests in Sordariaceae based on phylogenetic analyses (Wang et al. 2019a, b; this study).
