Flowering plants 10–20 cm tall. Leaf lamina appressed to the peduncle below the lowest flower. Inflorescence 1–4 cm long, dense. Flowers 5–50, green with a dark purplish-black labellum, c. 3.5 mm across, nodding; perianth segments not spreading widely; dorsal sepal broadly ovate, 2–2.5 mm long, c. 2 mm wide; lateral sepals slightly divergent, linear-lanceolate, 2.8–3.5 mm long, c. 1 mm wide, pouched at base; petals ovate, c. 2 mm long, c. 0.8 mm wide, margins entire, apex often gland-tipped. Labellum ovate to obovate, c. 2 mm long, c. 1 mm wide, margins minutely crenulate, apex obtuse; callus narrowly oblong to narrowly ovate-lanceolate, extending nearly to the labellum apex. Column wings scabrous. Flowers Feb.–May.

GipP, Glep, Gold, LoM, MuM, Wim. Apart from isolated occurrences near Portland, confined to more arid habitats of north-western Victoria, mostly in mallee shrubland and Callitris woodland.

Previously confused with C. nigricans, but that species has generally fewer, slightly larger, purplish brown flowers and the callus on the labellum is shorter. Corunastylis nigricans is apparently confined to Kangaroo Island and southern Eyre Peninsula in South Australia.
