Moss - Fotinalis spp.
THIS PAGE IS UNDER CONSTRUCTION.
This genus of mosses are dioecious submerged aquatics that attach to
the substrate at a single point. They are variously colored in greens,
browns, golden-browns, or golden-red. The stems are slender to robust,
branching above. The leaves are in 3 rows and lack a costa (midvein).
Depending on the species, the leaves are variable and may have the following
characteristics: erect or spreading, ovate to lanceolate, acute or blunt
at the apex, toothed at the tip, keeled, concave, flat, or auriculate.
The capsules are flattened mostly immersed. The peristome is double with
the endostome trellislike.
All the species grow submerged, most of them in swift running water.Dense
mats of water mosses can interfere with water flow in irrigation canals.
The plants can survive in both eutrophic and oligotrophic situations.
