VVP. Currently known only from the vicinity of the type locality in basalt plains grassland near Mt Mercer.

Similar in appearance to Prasophyllum frenchii, but generally less robust with more widely opening flowers and different structure of the labellum callus.

Prasophyllum fosteri has become critically endangered due to substantial loss of habitat.
