|discussion=<p><i>Pseudocalliergon trifarium</i> is easily identified by the unbranched or almost unbranched shoots with straight and imbricate or rarely more or less spreading, broadly or very broadly ovate leaves with broadly rounded apices. Shoots of <i>P. trifarium</i> are frequently divided into segments that correspond with growth seasons; in the proximal, spring portion of each segment the leaves are smaller and more strongly imbricate than distally in the same segment. The transition between the differently sized leaves is gradual within each segment, whereas the transition between segments is sudden. <i>Pseudocalliergon trifarium</i> could possibly be confused with <i>Loeskypnum wickesiae</i> (Calliergonaceae), and the characters separating these two species are given with the latter.</p>
