ABSTRACT. A new species, tentatively recognized within the moss genus Cynodontium, is described from the Baltic Amber based on well preserved plant gametophyte. Its overall habit, presence of distinct teeth in the leaf apex and recurved leaf margins resemble most modern species of the genus, although the characteristics of scattered papillae and absence of diagnostic characters precludes its unequivocal identification with any extant species. Among the acrocarpous moss taxa previously described from the Baltic Amber, the papillose cells were known only in Hypnodontopsis, a markedly smaller moss, with entire and not strongly channelled leaves.
