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 genus – Cocoonihabitus W.Y. Zhuang & Z.Q. Zeng
Notes – Cocoonihabitaceae was introduced as a result of the separate branching of two strains of a species, sister to species of Ophiocordycipitaceae and Flammocladiellaceae in a multi-gene phylogram (Zhuang & Zeng 2017). The species has long cylindrical asci with thick cap at the apex, penetrated by a narrow pore, characters which also exist in species belonging to Clavicipitaceae, Cordycipitaceae and Ophiocordycipitaceae. However, the characteristics of the ascomata, absence of stroma, ascospore features and habitats separated this new taxon from the other taxa. Therefore, Cocoonihabitaceae was introduced (Zhuang & Zeng 2017).
