|discussion=<p>In addition to the numerous highly branched paraphyllia, stems in <i>Hylocomiastrum umbratum</i> (but not <i>H. pyrenaicum</i>) also bear some scattered larger paraphyllia. These are more than twice the size of typical paraphyllia, are lanceolate-subulate with toothed margins, and closely resemble the foliose pseudoparaphyllia. Under a dissecting microscope these larger paraphyllia are clearly visible at 30× scattered among the shorter paraphyllia. In otherwise difficult specimens, the presence of these larger foliose paraphyllia can be used to distinguish <i>H. umbratum</i> from <i>H. pyrenaicum</i>.</p>
