Monotropsis Schweinitz in Elliott. Pigmy Pipes, Sweet Pinesap.

Key to Monotropsis

A genus of probably 2 species, mycoheterotrophic herbs, of se. North America. Monotropsis is heteromycotrophic, receiving its nutrition by association with a mycorrhizal fungus (which itself is associated with tree species, perhaps oaks or pines), the intertwined root mass and fungal mantle about 1-2 cm in diameter. There is a plausible case that the proper name for the genus is Schweinitzia Elliott ex Nuttall (Rose & Freudenstein 2014).
