It has only been documented in Mexico, in the states of Sonora and Estado de México. M. evangelinae is close to M. persoonii, with ascospores of 9–11 μm diam. (Sammut et al. 2023). The former has ascospores ornamented with a dense, complete, and united reticulum and asci of 120–200 × 12–13 µm, while the latter has ascospores with a complete reticulum, rarely incomplete and separated, with larger and tortuous meshes, and asci of 180–250 × 12–16.5 µm (Moravec 1987; Martínez-Gil and Caballero 2016; Olariaga et al. 2020).
