Cheilotheca is a small genus of myco-heterotrophic plants in the family (Ericaceae). They get the nutrients they need to survive and grow. They connect to the fungi, they get their nutrients from via their thin, white roots. All of the fungi they are parasites of all belong to the Russulaceae. As of currently, the genus includes three species.
