|discussion=<p>The small dark green plants of <i>Ptychomitrium incurvum</i> are unmistakable growing on rock, with their glossy leaves tightly crispate when dry. The leaves are shorter than in <i>P. sinense</i> and are straight when wet, not somewhat falcate at the tips as is common in <i>P. sinense</i>. Sporophytes are very common in this moss and the old sporophytes persist for a long time. Sterile colonies of <i>P. incurvum</i> can be very reminiscent of <i>Weissia controversa</i>, but <i>Ptychomitrium</i> is more glossy; its leaves have smooth cells and without the strongly involute margins of <i>Weissia</i>.</p>
