Notes – Chethana et al. (2015) introduced Pseudosplanchnonema for a splanchnonema-like species that was phylogenetically placed in Massarinaceae. The genus was found associated with dead branches of Acer campestre and Morus spp. in Italy and Russia. Pseudosplanchnonema is characterized by its immersed, ostiolate ascomata, 8-spored, clavate, 2-seriate asci and fusiform, dark brown ascospores surrounded by a gelatinous sheath with subglobose to oblong, hyaline, aseptate conidial mass produced in culture (Tanaka et al. 2005b, Chethana et al. 2015).
