Labellum 4–5 mm long, subsessile, recurved near middle, greenish, whitish or pink, base orbicular, flat, margins smooth; callus often greenish, prominently raised, covering most of labellum lamina and extending almost to the apex.

HNF, HSF, MonT, SnM, VAlp. Also NSW, ACT, Tas. Confined to alpine and subalpine meadows and snowgum woodlands, often in moist to wet areas among tussock grasses.
Formerly confused with P. alpinum, but that species has smaller, greenish flowers and is confined to Tasmania. Prasophyllum sphacelatum is a more robust species with larger flowers than P. tadgellianum and the leaf-blade is withered at flowering (still stiff and green in P. tadgellianum).
