Corallorhiza species -- "Coral root orchids". Five species are found in Yellowstone, shown below.

These orchids are saprophytic, having no chlorophyl to photosynthesize. They are usually found "in the dark with mosquitos" -- at least partial shade, and are sometimes hidden under other vegetation. My impression is that the western coral root is the most numerous in the park. See detail pages for Locations and approximate blooming times. These vary by species.
