Macromitrium densum Mitt. (from Nepal) is well differentiated from other Asian congeners by its lingulate and strongly rugose leaves having cucullate, obtuse to retuse apices with a mucro, distinctly bulging upper and median leaf cells, and tuberculate lower and basal cells. Comparisons of the type and other specimens of M. brevissimum Dixon from Thailand with those of M. densum show that they belong to a single species, and hence, that the names are synonyms. By including M. brevissimum, the geographic range of M. densum is considerably expanded to cover Nepal, Thailand to north Peninsular Malaysia and Vietnam. The phenetic relationship between M. densum and other species of Macromitrium is also discussed.
