How to recognize Bryum pseudotriquetrum: This moss grows in wet areas and forms dense tufts of little plants with rhizoids matting the stems well toward the tip of the stem. The leaves are 2-3.5 mm long and when moist spread somewhat away from the stem to straight up, but are twisted and contorted when dry. The leaf margins have a strong border of 2 to 3 rows of linear cells which are often red, and are recurved nearly to the apex of the leaf. These leaves are very decurrent which is a good indication that this might be Bryum pseudotriquetrum. The leaf costa is percurrent (almost to the tip) or short-excurrent. Sometimes there are filamentous brown brood bodies in the upper leaf axils.
Where to find Bryum pseudotriquetrum: It is commonly found on wet soil, soil over rocks, and often in fens.
