Luisierella barbula (Schwägr.) Steere

in Bryologist 48: 84. 1945. ( Pottiaceae)

Notes – Luisierella barbula was described from Cuba and most collections come from the West Indies and adjacent areas in Mexico and the south-eastern United States, but it is also known from Japan, Southeast Asia, and scattered islands in the Indian Ocean (Seychelles: Aldabra; Mascarenes: Rodrigues). Its strong affinity for limestone substrates is a likely explanation for its distribution.
