Doveri et al. (2010) introduced the monotypic genus Rodentomyces with R. reticulatus as the type, based on the phylogenetic analysis of ITS sequences. Rodentomyces reticulatus occurs in small rodent dung (Doveri et al. 2010). However, the genus name was not valid because the holotype was cited as ‘cultura viva’ in the original protologue (Doveri et al. 2010). Later, the name was validated in the Index Fungorum (2016). The genus is characterized by superficial, astromatic, ostiolate, and pale yellow to luteous ascomata that do not change colour in KOH. The peridium is less than 10 μm thick and is composed of thick-walled cells with angularis texture. Periphyses and apical paraphyses are present. Asci are unitunicate and inamyloid with an inconspicuous apical apparatus. Ascospores are yellowish brown, 1-septate to muriform, tuberculate, and subreticulate with no germ pores or slits (Doveri et al. 2010).
