Ovicuculispora was established by Etayo (2010a) and is characterized by producing two types of ascospores within a single ascus: macrospores and microspores. The type species, Ovicuculispora parmeliae, was transferred from Diplodia parmeliae Berk. & M.A. Curtis. This species is distinguished by its globose to subglobose ascomata, which are pink to red with a brighter papilla and a long-haired surface. The asci are clavate and contain one macrospore and four microspores. The ascospores are ellipsoid to narrowly ellipsoid, rounded at the apices, hyaline, and constricted at the septum. Macrospores measure 29.7–47.7 × 12.0–22.1 μm, while microspores are 6.6–11.2 × 3.1–5.9 μm (Flakus et al. 2019b, Tadome et al. 2021). Ovicuculispora parmeliae exhibits significant variation in macrospore size and has been documented on multiple hosts (Lawrey et al. 1994, Cole et al. 2001, Diederich 2003, Flakus et al. 2006, Etayo 2010b).

Only two species are recognized within the genus, both of which are lichenicolous. Although Telfer et al. (2015) submitted an ITS sequence labeled as Ovicuculispora parmeliae to GenBank, no phylogenetic analysis has yet incorporated this molecular data.
