EGL, HSF, HNF. Found in mountain forests of eastern Victoria, often in fern gullies and wet sclerophyll forests growing in rich mountain loam or on rotting logs or treefern trunks.
Corybas grumulus can be distinguished from C. diemenicus by its smaller flowers in which the labellum tube is significantly longer than the lamina, and the marginal teeth on the labellum are shorter.
