|discussion=<p><i>Racopilum tomentosum</i> is unmistakable due to the creeping stems, which are heavily tomentose ventrally in older portions, and the dimorphic leaves twisted-contorted when dry and spreading-erect in 4 rows when moist. Some of the Florida specimens have gametoecia (for example, Philips 97), but only a single collection with sporophytes is known from the flora area (Collier Co., Anderson & Crum 13440, Mosses of North America 595, DUKE, FLAS, LAF). Some duplicates of this issue may lack sporophytes.</p>
