|discussion=<p><i>Tetraplodon angustatus</i>, like <i>T. mnioides</i>, is mainly boreal in distribution and occurs on similar substrates; it is easily distinguished from <i>T. mnioides</i> by lanceolate-acuminate, irregularly serrate leaves that narrow to a slender, elongate acumen, shorter seta, and green (brown with age) hypophysis. In Alberta, sporophytes mature in spring prior to the maturation of <i>T. mnioides</i> sporophytes, resulting in the temporal separation of spores of these two species on fresh droppings and thus the physical separation of <i>T. angustatus</i> and <i>T. mnioides</i> on droppings where these two species occur together regionally.</p>
