|discussion=<p>The rather weak molecular differences of the North American <i>Homalothecium sericeum</i> from European material (S. Huttunen et al. 2008) and the limited distribution in Newfoundland suggest a rather recent migration of <i>H. sericeum</i> to North America. The closest stations are in Iceland, 2500 km from Newfoundland. <i>Brachythecium laetum</i> also has opaque basal cells, but it never develops recurved teeth along the leaf margins in the alar region.</p>
