This fascinating plant (Monotropa uniflora)

It was formerly classified in the family Monotropaceae, but is now included within the Ericaceae. It is of ephemeral occurrence, depending on the right conditions (moisture after a dry period) to appear full grown within a couple of days.

Unlike most plants, it is white and does not contain chlorophyll.[4] Instead of generating food using the energy from sunlight, it is parasitic, and more specifically a mycoheterotroph. Its hosts are certain fungi[4] that are mycorrhizal with trees, meaning it ultimately gets its food 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. It is often associated with beech trees.[5] The complex relationship that allows this plant to grow also makes propagation difficult.
