NIS, EGU, HNF, MonT, VAlp. Also Qld, NSW, ACT. Found in drier highland areas in the far north-east and rainshadow areas of the upper Snowy River, usually in sheltered sites within open-forest.
Of Victorian Corybas species, C. hispidus is the earliest flowering, usually finishing as the closely related C. fimbriatus is just beginning. The hairy and deeply notched, white patch in the middle of the labellum is a conspicuous feature of the species, which distinguishes it readily from C. fimbriatus.
