Stevens et al., 2016 has resurrected this subfamily from the tribe (Pyroleae) in Monotropoideae on two grounds;
- The two clades diverged 70/79 MYA.
- There are significant differences in their myco-heterotrophic behaviour. This subfamily are facultative parasites and normally have functional leaves or retain these when parasitism is difficult. Whereas genera in the Monotropoideae are obligate parasites and achlorophyllous.
