Type species – Crassiparies quadrisporus M. Matsum., K. Hiray. & Kaz. Tanaka., Fungal Divers. 78: 63 (2016).
Notes – Crassiparies is a monotypic genus with C. quadrisporus, a putative saprobe on twigs of Acer sp. (Li et al. 2016a). The generic name of Crassiparies, was a combination of the Latin “crassi-“ meaning thick and “paries” meaning wall, referring to the thick ascomatal wall of this fungus (Li et al. 2016a). Initially Crassiparies was introduced as Pleosporales, genera incertae sedis. Crassiparies is similar to Massarina as both genera have cylindrical, bitunicate asci and broadly fusiform, 1-septate, hyaline ascospores. Crassiparies has thick ascomatal walls, ascomatal neck without clypei, and 4-spored asci. C. quadrisporus may occur in various plant species as saprobes and endophytes, and are widely distributed in temperate and tropical regions. However, a reexamination of specimens revealed that this species actually has thin-walled ascomata (Tanaka et al. 2017).
