Sphagnum genus (Moss). Sphagnum mosses came in a variety of shapes, sizes and will grow in many different habitats. If you want to distinguish the individual species, you must closely examine the leaf shapes with a magnifier, although some general features such as the length of the branches will indicate the most likely species. Sphagnum is known by the unique branching system, with its distinct stem and branch leaves and the spongy masses of cushions in bogs and wet places. The ripe capsule is raised on a short stalk, which is widely ovoid or globose. It lacks a peristome. Eventually there is a lateral shrinkage of the wall with the result that an internal air pressure is set up and the lid is finally blown off and spores are released explosively.
