|discussion=<p><i>Ptychostomum turbinatum</i> is a circumpolar arctic-boreal to temperate species. The dull green to yellow-green shoots, strongly shrunken ovate-lanceolate leaves, and turbinate capsule are diagnostic. Old capsules often turn black and become strongly constricted just below the mouth. The stems are sparsely radiculose, sometimes with clusters of rhizoids arising from the proximal leaf axils. <i>Ptychostomum schleicheri</i> is much larger, pale yellow distally, with wider leaves and much wider distal laminal cells. Large specimens, 8–12 cm, with long narrow ovate-lanceolate leaves and elongate-pyriform capsules, represent an undescribed species.</p>
