Discussion

Besides having different branch leaf porosity, Sphagnum cribrosum is usually distinguishable from the closely related S. macrophyllum by its paler brown color and distinctly broader and more truncate branch leaves. “Wave forms” of both S. cribrosum and S. macrophyllum, seemingly developed in response to growing in shallow water where wave action is common, can have very odd phenotypes that may look more like Fontinalis than Sphagnum.
