Indian Pipe, monotropa uniflora, also known as the ghost or corpse plant. Such a fascinating plant! And I think very appropriate for the time of year. I found these growing in a forest north of where I live. I’ve never seen them again since.
It seems that many cultures have seen these plants as ghostly parasites, though often used for healing a wide array of ailments, they were known to be connected to the spirit world.
It is in fact a parasitic plant, because it doesn’t produce chlorophyll it instead feeds off of plants that do. It is very rare.
