First records of bryophilous myxomycetes in the lowlands of Ukraine reveal an undescribed species of Lamproderma.

Bryophilous myxomycetes are found mainly in humid mountainous regions, particularly in the Ukrainian Carpathians. Over the last three seasons, three species from this group (Colloderma oculatum, Diderma tigrinum, and Lamproderma sp.) have been discovered in Slobozhanskyi National Nature Park, a lowland region in the forest-steppe zone of north-eastern Ukraine. These finds indicate an expansion of the distribution range of bryophilous myxomycetes beyond their typical montane and boreal habitats. The unidentified species of the genus Lamproderma, related to L. muscicola, exhibits distinct morphological and molecular characteristics sufficient to consider it a separate species.
