Fontinalis antipyretica
Also called Greater Water Moss, Willow Moss
Fontinalis antipyretica, the greater water moss, is a submerged aquatic moss that grows attached to rocks or floating in still and flowing freshwater. It is grown in ponds and aquariums where it is kept cool, shaded, and in water with suitable pH.
Fontinalis antipyretica, greater water-moss, or common water moss, is a species of submerged aquatic moss belonging to the subclass Bryidae. It is found in both still and flowing freshwater in Europe, Asia, Greenland and Africa. In North America it is found in most Canadian provinces with a seaboard and most US states except the most southern.
F. antipyretica is found in Europe, Asia and parts of Africa. It grows attached to submerged rocks in fast-flowing water. It also occurs attached to the substrate in lakes and as floating masses in still water, and may be cast up on beaches at the waterside. It thrives in shady positions and prefers acidic water, with a pH of around 8.4 being the maximum tolerated. It is replaced in highly acid mountain and moorland streams in the UK by Fontinalis squamosa.
