In general, moss looks fibrous, feathered or latticed when viewed up close. Carpets of moss are springy to the touch. When germinating, moss puts up thin stems sometimes with leaves on top and reproductive spores. Algae have no threadlike structures or leaves. Instead, algae spread as a clump of living cells. Because algae usually grow in wet environments, they look like a slimy, wet mass, often green in color. Both moss and algae may appear green or brown depending on species and the dryness of the conditions.
