Notes – The generic concept of Stagonospora was originally defined in Castellani & Germano (1977) with keys to species provided by Sutton (1980). The genus was mentioned as related to Phaeosphaeriaceae (Zhang et al. 2012b). However, molecular data coupled with morphological resemblance of the type species of Stagonospora, (S. paludosa) showed that the genus has an affinity with Massarinaceae (Quaedvlieg et al. 2013). According to phylogenetic results, a single strain of Neottiosporina paspali clustered with Stagonospora members (Sutton & Alcorn 1974, Quaedvlieg et al. 2013, Tanaka et al. 2015, Thambugala et al. 2017b). The strain should be treated under Stagonospora, however the generic sequence data of Neottiosporina is required. Stagonospora is characterized by its ascomatal wall of textura polygonal to textura subglobosa, oblong asci with short, simple pedicel, hyaline ascospores with pycnidial asexual morph. Stagonospora was originally described for the asexual morph (Sutton 1980), and the sexual morph characters were recently documented in Tanaka et al. (2015) and Crous et al. (2017a).
