The Calymperaceae (Musci) are largely restricted to the tropics and subtropics worldwide. This family of acrocarpous mosses, mostly dioicous, with erect stems and predominantly corticolous, is characterized by the uniform presence in the clasping leaf bases of cancellinae, lack of stem central strand, mostly thickened and toothed leaf margins, peristome single (or lacking), and common production of uniseriate gemmae on the leaves. Includes keys, descriptions, line drawings, and destribution maps. / Leucophanes, the only genus in the Leucophanaceae, is revised for Central America, the Caribbean, and South America. The most characteristic feature of the gametophyte in Leucophanes is its leaf structure. Includes descriptions, line drawings, distribution maps, and habitat information.
