Platyhypnidium Moss
Rhynchostegium riparioides
Platyhypnidium riparioides, the long-beaked water feathermoss, is a species of aquatic moss commonly found in many regions. This species is among the largest aquatic mosses growing up to 15 cm long. P. riparioides grows in a procumbent or pendulous fashion along rocks and tree roots and may form extensive lax mats of many intermingled plants. It is widely distributed South of the Arctic and can grow abundantly in suitable areas.

Description
Platyhypnidium ripariodes is among the larger northern hemisphere mosses with leaves up to 8mm long and plants growing up to 15 cm long. In the UK, plants commonly produce calyptra with relatively long curving lids. The leaf tip is acute, leaf margins are plane, slightly denticulate towards tip, mid-leaf cells are large, costa or the central stork of the leaf extends nearly to leaf tip. The growth form is procumbent but small, young plants can attach themselves closely to rocks and appear flattened.
