Sphagnum cuspidatum moss, and to avoid contact with the moss against scraped or cut skin. The moss prefers damp conditions, and is relatively hardy in peat bogs. It does not perform as well in completed submerged conditions as it is incapable of producing sufficient amounts of chlorophyll to grow extensively, and natural causes also result in the death of new shoots produced. Like most species of "Sphagnum", this moss has mild antiseptic capabilities. It is very absorbent and acidic, and therefore creates environments not suitable for bacterial growth. These mosses were used up until World War I to pack wounds on the
Moss in cities. Examples would be "Rhytidiadelphus squarrosus", a garden weed in Vancouver and Seattle areas; "Bryum argenteum", the cosmopolitan sidewalk moss, and "Ceratodon purpureus", red roof moss, another cosmopolitan species. A few species are wholly aquatic, such as "Fontinalis antipyretica", common water moss; and others such as "Sphagnum" inhabit bogs, marshes and very slow-moving waterways. Such aquatic or semi-aquatic mosses can greatly exceed the normal range of lengths seen in terrestrial mosses. Individual plants or more long are common in "Sphagnum" species for example. Wherever they occur, mosses require liquid water for at least part of the year to complete
