I've come across the very cool and most unique Indian Pipe, Monotropa uniflora, in a couple of locations around the lake.
"Unlike 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."
