Description
British soldier lichen is widespread in eastern North America. Branching stalks with bright red knobs at their tips arise from a patch of small, green scalelike structures. The red is similar to the color of British soldiers’ coats during the American Revolution.

Description
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.

With their flattened, green forms, hornworts resemble liverworts, but their spore-bearing structures are elongated and horn-shaped. As with liverworts and mosses, hornworts make forest floors, streamsides, and spring openings beautiful.

Snakeskin liverwort looks like large, flattened, irregular, overlapping straps. The surface is covered with polygon-shaped air pores, giving it a bubbly appearance similar to snakeskin. Look for it along streams, springs, and the moist bases of bluffs.

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.
