ABSTRACT. Molecular phylogenetic analyses based on nad5, rps4 and trnL-F sequences suggest the position of the genus Hymenoloma in the order Scouleriales. This order includes two monogeneric families: Scouleriaceae, with aquatic plants, and Drummondiaceae that includes mostly epiphytic mosses. Mainly epilithic Hymenoloma strongly differs from both of them, as well as they differ from each other, thus a new family Hymenolomataceae is suggested for this genus. Morphologically, Hymenoloma has no unique characters, although its outstanding plasticity provides some explanation of its relationships with Scouleria and Drummondia.
