Mosses are primitive, spore-producing plants found most often on shaded, moist surfaces. They form thick mats of foliage, roots, and a dense buildup of organic matter below. Most kinds are perennial, possibly with the foliage desiccating in hot, dry weather. Propagation is either from wind-blown spores or from vegetative spread. The spores are produced in visible capsules that form at the ends of the leafy shoots.
In turf they generally grow in weakened, bare areas. Heavy moisture encourages the growth of mosses.
