(540.) M. decurrens, C. M. & Kindb. (n. sp.); Canadian Musci, No. 517.

Dioecious. Loosely tufted. Stem very loosely foliate, naked below, elongate. Leaves green or finally reddish, subdistichous, long-decurrent, often red at the margins and the wings, doubly dentate, lanceolate, the inner perichetial ones sublinear, red-cuspidate; cells smaller than in Mnium umbratile; costa sub-percurrent, often red, in the inner perichetial leaves excurrent.

(545.) M. Niagarae, Kindb. (n. sp.); Canadian Musci, No. 581.

Perichetial leaves narrow sub-linear, dentate, the innermost very short. Capsule solitary, pendent, narrow, often appressed to the pedicel, subclavate-cylindric, constricted below the wide mouth; teeth yellow; lid obliquely rostrate; pedicel pale-red.
