Abstract
Two species of nivicolous myxomycetes, Lamproderma pseudomaculatum and Lamproderma aff. pulchellum, previously considered as strictly montane, are reported from the lowlands (116–192 m a.s.l.) of the eastern Ukraine during three spring seasons. Lowland collections of L. aff. pulchellum show comparatively low genetic similarity with specimens of this species collected at high elevations and may represent a new taxon. Autumn frosts, which occurred before the formation of a stable snow cover, as well as the limited number of days with snow cover exceeding 30 cm, did not prevent the abundant fruiting of these myxomycetes.
