Gray Reindeer Lichen (Reindeer Moss)
Cladina rangiferina (syn. Cladonia rangiferina)
Gray reindeer lichen, also called reindeer moss, takes the form of bright ashy or silvery-gray, branching cushions that grow on the soil. The branch tips usually bend to point in the same direction, as if combed or blown by a strong wind.

About Mosses, Liverworts, and Lichens in Missouri

Mosses, liverworts, hornworts, and lichens seem rather similar, but these organisms are in very different groups. Mosses, liverworts, and hornworts are small, low plants usually found in damp habitats. Unlike more familiar plants, they lack veinlike structures and do not produce flowers or seeds — instead, they produce spores. Meanwhile, lichens are not plants at all: they are a collection of different fungi that have photosynthetic algae living within their tissues.
