This species isn't common in Hungary but not so rare either. I found a lot of specimens in October, in various deciduous forests in the Bükk mountains. All Hygrophorus species need mycorrhiza partner, so they can only live on the dunes if their partner also grows there. This species is mostly connected to oaks, but some other species have different partners. For example the obligate tree partner of Hygrophorus pudorinus is fir (Abies spp.), H. hypothejus lives under 2-needle pines (Pinus spp.), H. lindtneri under hornbeam (Carpinus spp.) and so.
