Ectomycorrhizal species strictly associated with Alnus spp. (A. glutinosa, A. incana, A. alnobetula), in riparian forests and swampy places, localities scattered and endangered by degradation of habitat (pollution by nitrogen, destruction of riparian forests…).
Population Trend: Uncertain
Alnus glutinosa, Alnus incana, Alnus alnobetula, in natural, mesotrophic to meso-eutrophic alder stands
Regression of a specific habitat (mainly Alnus glutinosa in regularly flooded areas); sensitive to nitrogen.
Preserve stable riparian areas and favourable species-rich alder stands in wetlands.
