This monotypic genus was erected since the newly acquired strains of the freshly collected fungus, namely, Cocoonihabitus sinensis, clustered independently in the phylogenetic tree, apart from the other genera in other families (Zhuang & Zeng 2017). Cocoonihabitus sinensis shares morphological resemblance to taxa belonging to some genera in Clavicipitaceae and Ophiocordycepitaceae in terms of asci and ascospores. However, the ascomata of C. sinensis are astromatic and seated directly on the substrate, contrary to the ascomata of the species in the other genera of Clavicipitaceae and Ophiocordycepitaceae, which are mostly immersed or semiimmersed (Zhuang & Zeng 2017).

Type species: Cocoonihabitus sinensis W.Y. Zhuang & Z.Q. Zeng.

Other accepted species: Species Fungorum – search Cocoonihabitus.
