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.

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.
