|discussion=<p><i>Pilosium chlorophyllum</i> is rarely confused with other species in Stereophyllaceae. The species is distinctive because of its glossy, complanate-foliate plants, and dimorphic leaves, the dorsal ones symmetric and oblong-ovate, with neither a costa nor a distinctive alar region of differentiated cells, the lateral ones cultriform and oblong-lanceolate, with a short, weak costa scarcely reaching 1/3 leaf length, and a large area of enlarged, pigmented alar cells on one side of the costa. The cernuous, short-cylindric capsules have collenchymatous exothecial cells and the spores, 7–9 µm, are smaller than in other members of the family.</p>
