Coprophilous. Sexual morph: Ascomata perithecial, gregarious, superficial to semi-immersed, ovoid to subglobose, brown to black, membranaceous to carbonaceous, ostiolate, with central papilla, periphysate. Peridium composed of brown cells of textura angularis. Paraphyses numerous, filiform, flexuous, septate. Asci 8-spored, unitunicate, cylindrical, pedicellate, apex truncate, with apical ring, evanescent. Ascospores uni-seriate, broadly ellipsoidal to ovoid, with an apical germ pore, hyaline when young, becoming upper cell aseptate, brown to dark brown, with plate-like wrinkles on surface when mature and truncate at the base; lower cell tiny, hyaline conical. Asexual morph: Undetermined (adapted from Lundqvist 1972).
Notes: Jugulospora is typified by J. rotula and characterized by ovoid ascomata and ovoid ascospores with a gelatinous cap-like cell at the base and a plate-like wrinkles (Lundqvist 1972). Marin-Felix et al. (2020) transferred this genus to Schizotheciaceae and introduced three more species, J. antarctrica, J. carbonaria and J. vestita based on morphology and phylogenetic analysis. This study also confirms that Jugulospora strains nest in Neoschizotheciaceae (56%ML/1.00PP).
Type species: Jugulospora rotula (Cooke) N. Lundq., Symb. bot. upsal. 20(no. 1): 260 (1972).
Other accepted species: Species Fungorum – search Jugulospora.
