Plants small to medium-sized, pale green. Stems 4-10 cm, yellowish green to pale brown, creeping, ascending, or erect, , densely to sparsely pinnate, branches0.4-0.7+ cm; hyalodermis absent, central strand weak; pseudoparaphyllia filamentous to lanceolate, occasionally 2-fid.

Hypnum jutlandicum 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 H. imponens, but H. jutlandicum has yellow rather than red-brown stems and golden yellow rather than pale yellow leaves. The pseudoparaphyllia of H. imponens are more broadly foliose than the nearly filiform ones of H. jutlandicum. Distinction from H. cupressiforme is less apparent, but the usually more complanate pale green plants of H. jutlandicum are usually sufficient to separate it. Plants of H. jutlandicum 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.
