Notes – Morphological characteristics of Pseudoasteromassaria are similar to Asteromassaria (Pleomassariaceae) (Tibpromma et al. 2017). Both sexual and asexual morphs are recorded for this genus (Tibpromma et al. 2017). The genus contains two species collected from Japan and Thailand as parasitic on twigs of Fagus crenata and saprobic on submerged wood in freshwater habitats, respectively (Ariyawansa et al. 2015a, Tibpromma et al. 2017). The genus is characterized by scattered, immersed, globose ascomata, 8-spored, bitunicate, fissitunicate, cylindric to clavate asci and 2–3 overlapping seriate, brown, fusiform, 1–3-septate ascospores (Ariyawansa et al. 2015a).
