The mycorrhizal synthesis between Dryas octopetala L. and two Agaricales from alpine area: Hebeloma alpinum (Favre) Bruchet and Hebeloma marginatulum (Favre) Bruchet, have been produced in the laboratory. Both fungi yielded normal fructification after 8 months in culture. After light and scanning electron microscopic examination, macro- and microscopical features of these mycorhizae are described. This symbiotic association, existing in the field between D. octopetala and those fungi typical of the alpine area, is discussed from an ecological point of view.
