|discussion=<p><i>Cyrto-hypnum pygmaeum</i> is the smallest species of the genus in the flora area; the diminutive stature coupled with papillose stems and branches is distinctive. The species is most likely confused with <i>Heterocladium macounii</i> (Pterigynandraceae), which also has multipapillose laminal cells and papillose stems and branches. However, <i>H. macounii</i> is larger and has a costa ending near or before mid leaf and is without paraphyllia; pseudoparaphyllia are present, but these have pointed apical cells, not truncate as are the paraphyllia cells of <i>C. pygmaeum</i>.</p>
