ABSTRACT. A morphological and molecular phylogenetic study of a peculiar Solenostoma from Alaska with emarginate to lobed leaves and long purple rhizoids revealed an unknown species. The species is described as Solenostoma alaskanum sp. nov. It is characterized by medium-sized plants, numerous, very long, rigid and sporadically dense, dark purple to dark red-brown rhizoids, mostly short two-lobed or emarginated, rounded-quadrate to oblong leaves, distinct hyalodermis, large granulate oil-bodies and trnL-F and trnG-intron sequences other than in closely related species. The differences from morphologically similar species with bilobed or emarginate leaves and purple rhizoids occurring in Western North America, are discussed.
