There are two relatively small and unusual looking plants found in NCR parks that might be mistaken for fungi arising from the forest floor. These are Indian Pipe (or Ghost Pine) and Squawroot (also called Cancer Root). Both are most likely to be encountered in forests with at least some oaks present, although only the latter is always associated with oak, since it is parasitic on the roots of oak trees. Squawroot (Conopholis americana) has been general appearance of an upright pine cone sticking out of the ground or, if one has a lot of imagination, a somewhat weird looking morel. The portions of the plant that project about the ground are usually about 6 in (15 cm) tall. Indian Pipe (Monotropa uniflora) is about the same height or a little taller and completely white when young, although with increasing age the color changes to pink and then finally black.
