Nearly allied to Bryum Warneum, agreeing in the peculiar peristome and the very large spores, about 0.05 mm.,etc, but differing principally in the leaves being longer acuminate, entire, revolute at the borders, the costa long-excurrent, the capsule narrower and the lid lower; flagelliform branches absent. Monoecious.

On damp, sandy soil close to the sands of Brackley Beach, Prince Edward Island, July 7th, 1888. (Macoun.)

(466.) B. brachyneuron, Kindb. Ott. Nat. Vol. V., p. 180.

Agrees with Bryum pendulum in the synoecious inflorescence, the peristomes orange, the segments adhering to the teeth, the apiculate lid and large spores (about 0.04 mm.); differs in the leaves being decurrent, short-ovate, the costa broad, abbreviate, not excurrent, the shoots bearing globose buds (gemmae), the very much broader peristomial teeth. Stem red, very short; the pedicel about 1 cm. long or shorter, often scarcely emerging above the tufts; costa of the lowest leaves red, percurrent only in the leaves of the shoots and the periche-tial ones; capsule ventricose, short-necked, constricted below the mouth.

Bryum fallax, Milde, resembling it in habit, is dioecious; the segments are free, the spores smaller. Bryum lacustre differs in the not decurrent leaves, the capsule not constricted below the mouth, the pedicel is longer and the peristome is pale, etc.
