AppearanceThe plant is sometimes completely white but commonly has black flecks and a pale pink coloration. Rare variants may have a deep red color.
The stems reach heights of 10–30 cm, clothed with small scale-leaves 5–10 mm long. As its scientific name suggests, and unlike the related ''Monotropa hypopitys'' , the stems bear only a single flower, 10–15 mm long with 3-8 petals. It flowers from early summer to early autumn.
NamingLike most mycoheterotrophic plants, ''M. uniflora'' associates with a small range of fungal hosts, all of them members of Russulaceae.

Leaves are scale-like, without chlorophyll, alternating on a waxy stem.
Each of ten anthers open via two curving slits.

BehaviorUnlike most plants, it is white and does not contain chlorophyll. Instead of generating energy from sunlight, it is parasitic, more specifically a myco-heterotroph. Its hosts are certain fungi that are mycorrhizal with trees, meaning it ultimately gets its energy from photosynthetic trees. Since it is not dependent on sunlight to grow, it can grow in very dark environments as in the understory of dense forest. The complex relationship that allows this plant to grow also makes propagation difficult.
