|discussion=<p><i>Hypnum jutlandicum</i> is largely an amphi-Atlantic species that may occur in Alaska. The pale yellowish green, glossy, pinnate plants are very distinctive; they might be confused with <i>H. imponens</i>, but <i>H. jutlandicum</i> has yellow rather than red-brown stems and golden yellow rather than pale yellow leaves. The pseudoparaphyllia of <i>H. imponens</i> are more broadly foliose than the nearly filiform ones of <i>H. jutlandicum</i>. Distinction from <i>H. cupressiforme</i> is less apparent, but the usually more complanate pale green plants of <i>H. jutlandicum</i> are usually sufficient to separate it. Plants of <i>H. jutlandicum</i> have branches emerging in a horizontal plane; the pseudoparaphyllia are terminated by a 1-seriate tip of several elongate cells; the alar cells are usually strongly excavate and sometimes brown; and the distal laminal cells are subquadrate and 3–5(–7) along the margin.</p>
