Discussion

Plants of Ptychomitrium sinense are dark green and glossy; the leaves are tightly crispate when dry with the tips often circinate. The glossy pale or often brownish costa is very conspicuous in dry plants and is especially characteristic for this moss. When moist the leaf tips tend to be involute-cucullate and often falcate or somewhat uncinate.
