Sphagnum The moss inhibits the growth of microbes and reduces the need for chlorine in swimming pools. In New Zealand, both the species "S. cristatum" and "S. subnitens" are harvested by hand and exported worldwide for use as hanging basket liners, as a growing medium for young orchids, and mixed with other potting mixes to enhance their moisture retaining value. Peat moss is a critical element for growing mushrooms. The fungal mycelium grows in compost with a layer of peat moss on top, through which the mushrooms come out, a process called casing. Peat moss, dead or alive, is also a
Aulacomnium palustre plant communities, and individual moss species often have low cover and/or frequency. Moss species with coverages of 2% to 4% can be common to dominant in boreal communities, although ribbed bog moss attains coverages as great as 40% in some boreal communities. Ribbed bog moss grows in open and forested wetland communities. In unforested northern communities, ribbed bog moss is found in sedge ("Carex" spp.) meadows, sphagnum ("Sphagnum" spp.) peatlands, heath-sedge fens, and willow ("Salix" spp.)-dominated fens. In forests, ribbed bog moss grows in the ground layer of boreal and subboreal white spruce ("Picea glauca"), black spruce ("P. mariana"), mixed
