The Plumed Midge-orchid is a terrestrial orchid growing to 20 cm high (Jones in Harden 1993).

This species was originally described from Kurnell, NSW but had not been seen since, despite much searching, until it was rediscovered in the Marulan area (Bishop 1996). The species is presently known from six colonies, all located on private property near Tallong, east of Marulan on the southern boundary of the NSW Central Tablelands. These colonies are in remnant bushland, but close to rural, residential and other developments. The total population size is estimated to be several hundred individuals (Briggs pers. comm. in NSW NP&WS 1999d).

A morphological examination of the Genoplesium group showed that Genoplesium is monotypic (represented by a single species) and that Corunastylis should be recognised for the majority of species in the group (Jones et al. 2002).

Corunastylis plumosum (previously Genoplesium plumosum) is similar to G. sagittiferum which has a broader, shorter, obovate labellum. G. sp. aff. sagittiferum (southern NSW), which grows with G. plumosum, also has a broader and shorter labellum and has dirty green lateral sepals marked with red (Bishop 1996).

This species grows in heathland, dry sclerophyll forest, and in moss gardens over sandstone sheets. It can also grow on roadside verges (Bishop 1996; Jones in Harden 1993).

There is conflicting information on the flowering time of this species. Jones (in Harden 1993) lists the flowering time as Dec. to Mar. Briggs (in NSW NP&WS 1999d) states flowering time as Mar. and Apr.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
