Type species: Rhexothecium globosum Samson & Mouch., Can. J. Bot. 53(16): 1637 (1975).

Notes: Rhexothecium globosum was found from desert soil in Egypt. The genus is characterised by sphaerical ascomata with a pseudoparenchymatous peridium, clavate 8-spored asci and yellow to yellow-brown sphaerical ascospores. The asexual morph of Rhexothecium is hyphomycetous and described as trichosporiella-like. Hyde et al. (2013) accepted Rhexothecium as a genus in Eremomycetaceae. Cultures and sequence data are available but lacking for the type species.
