Cocoon‐inhabiting. Sexual morph: Ascomata superficial, solitary to aggregated, each seated on host directly or on a small basal stroma, perithecial, coriaceous, pale orange to orange, not changing colour in 100% lactic acid and 3% KOH. Peridium usually composed of 3 layers. Asci cylindrical, with a thick cap at the apex penetrated by a narrow pore, short pedicellate. Ascospores filiform, hyaline, multiseptate. Asexual morph: Undetermined (adapted from Zhuang & Zeng 2017).
Type species: Cocoonihabitus sinensis W.Y. Zhuang & Z.Q. Zeng, Mycosystema 36(12): 1594 (2017)
Notes: 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 semi-immersed (Zhuang & Zeng 2017).
