|discussion=<p>The stems and branches of <i>Papillaria nigrescens</i> are terete-foliate, dull, yellowish green, and often blackish in older portions. The plants creep over bark substrates and sometimes have elongate, irregularly branched, pendent branches. In some colonies of <i>P. nigrescens</i>, leaves of all plants have long, 1-seriate, filiform apices so that plants very much resemble <i>Barbella pendula</i>. Although perigonia are present in some specimens, no perichaetia or sporophytes have been found in plants from the flora area. Plants referred to as var. donnellii represent an apparently casually expressed form in which some branches lose their leaves, except for a tuft at the tip of the otherwise naked setalike branch. <i>Papillaria nigrescens</i> is common and often locally abundant throughout most of Florida, much less so in southern Louisiana.</p>
