Cryptomarasmius contains the term “crypto,” meaning “hidden,” and it is combined with another word, Marasmius. This alludes to the historical association of the species with Marasmius as well as the frequently concealed, diminutive fruit bodies they generate. This genus was established by Jenkinson et al. (2014) and typified with Cryptomarasmius corbariensis. Cryptomarasmius is characterized by diminutive, marcescent, convex basidiomes, ranging from smooth to rugulose, occasionally spinulose, and may even or striate. They are dry, typically darkly pigmented, and pallid infrequently. The lamellae range from vein-like to well-developed, seldom absent, and possess a smooth hymenophore. They are free to adnate, never collariate, and remote to subdistant, appearing pallid. The central stipe is rarely absent and is wiry-filiform, touand gh, insititious, glabrous, or pruinose, becoming darkly pigmented at maturity. Basidiospores are ellipsoid to fusoid or lacrymoid, smooth, hyaline, inamyloid, and thin walled. They appeared white in the deposits (Yasin et al. 2008, Jenkinson et al. 2014, Bozok et al. 2018, Dutta & Acharya 2018).
