Silvery Thread Moss
moss, silver moss
Moss appears as tufts or patches of finely textured plants and is usually associated with excess surface moisture as a result of frequent irrigation cycles, heavy shade, or poor surface drainage. Silvery thread moss is the most common species found in turfgrass, usually appearing on putting greens and in shaded back yards. Moss is commonly observed in the dominant gametophyte generation which is comprised of tightly packed individual male and female plants. Fertilization of the female plants is facilitated by moving water or traffic. The sporophyte generation grows parasitically on top of the mother plants. When mature, the fruiting body explodes, disseminating the spores for future generations. Asexual reproduction occurs by breaking away small fragments of moss; this process is called fragmentation. This vegetative spread is probably very common in turf via foot traffic and mowing.
