Isolated from soil. Sexual morph: Ascomata perithecial or without an external opening, superficial, globose to pyriform, yellow to brown, membranaceous, glabrous or setose, with or lacking ostioles. Necks conical, with crown of setae surrounding the ostioles. Peridium composed of yellow to pale brown cells of textura angularis, membranaceous. Asci 8-spored, unitunicate, broadly clavate, evanescent. Ascospores irregular or bi-seriate, aseptate, hyaline becoming brown to dark brown, broadly fusiform to citriform, umbonate and truncate at both ends, smooth-walled, germ pore with a raised rim at each end, mostly with guttules. Asexual morph: Conidia hyaline, subglobose to ovoid, smooth-walled (adapted from Marin-Felix et al. 2018).
Notes – Dactylidispora was introduced based on Sphaerodes ellipsospora and S. singaporensis and, those two are sister to Melanospora kurssanoviana based on phylogenetic results (Marin-Felix et al. 2018). This genus is characterized by citriform ascospores with a germ pore surrounded by a raised rim at each end (Marin-Felix et al. 2018). These features are similar to Pustulipora and Vittatispora; although Pustulipora has ascomata without neck and 4-spored asci (Cannon 1982), and Vittatispora has a hyaline ridge between the germ pores on ascospores (Chaudhary et al. 2006). In this study, Dactylidispora species clustered in Ceratostomataceae (80%ML/1.00BY).
