Type species –
Rhagadostoma corrugatum Körb.
Notes –
Rhagadostoma was established by Rhagadostoma corrugatum and has clavate, 2–4- spored asci and cylindrical ascospores with 1 septum (Körber 1865). The lichenicolous genus, Rhagadostoma, was considered as a member of Sordariales (Navarro-Rosinés & Hladun 1994, Navarro-Rosinés et al. 1999) and Huhndorf et al. (2004a) proposed a possible relationship with Bertia. Maharachchikumbura et al. (2016b) accepted this genus in Nitschkiaceae.
