|discussion=<p><i>Luisierella barbula</i> usually grows in a thin crust associated with cyanobacteria, <i>Hyophiladelphus agrarius</i>, and <i>Weissia jamaicensis</i>, the minute black plants contrasting starkly with the usually chalky white rock surface. The somewhat elevated cells on the adaxial surface of the costa may resemble a differentiated structure (a pad of cells), but the cells appear to be otherwise undifferentiated from those of the lamina.</p>
