Trichia sordida Johannesen represents the ecological guild of nivicolous myxomycetes, which occurs in mountainous areas at the edge of melting winter snow cover. It is not very common in the Northern Hemisphere and has never been reported from Poland. In the spring of 2020, two specimens of it were found in the Tatra Mts, in spruce forest close to the Polana Upłaz meadow on the Ciemniak massif (49°15′05.0″N, 19°52′46.4″E; Figs 1, 2). Together with the newly reported species the list of nivicolous myxomycetes reported from the Tatra Mts numbers eleven species. Trichia sordida is also reported for the first time for the entire Carpathian range.
