|discussion=<p><i>Hypnum dieckei</i> is distributed around the north Pacific and can be frequent on logs or outcrops near streams. The plants are distinctive especially in summer when sporophytes are produced, because <i>H. dieckei</i> is the only North American species with nodding capsules. The dark stems and pinnate branching associated with excavate alar regions of thin-walled cells set off by inner thick-walled and pigmented basal cells are also usually enough to distinguish <i>H. dieckei</i>. Plants of <i>H. dieckei</i> have branches 0.5–1.5 mm wide. They are often firmly attached by rhizoids, but the rhizoids are usually absent from suberect plants; the alar cells are 40–65 × 20–30 µm and often bulging, with the outer cells somewhat collapsed inward; the supra-alar cells are few and triangular; and the basal laminal cells are rectangular.</p>
