Ectomycorrhizae (ECM) of Lactarius aff. omphaliformis Romagn., Russula alnijorullensis (Sing.) Sing. and Cortinarius tucumanensis Mos. on Andean alder (Alnus acuminata Kunth), were characterized and identified. The identification of the fungal symbionts was achieved by morpho-anatomical observations of mycorrhizae, and by comparison of ITS-RFLP patterns obtained from ECM and fruitbodies. L. aff. omphaliformis ECM differed in some morphological details such as ramification  and mantle type from ECM of the same species on A. glutinosa. L. aff. omphaliformis ECM show an orange to ochre colored mantle containing latex cells, which stain with sulpho-vanillin, and emanating hyphae without clamps. R. alnijorullensis ECM represent a typical Russula-type-ECM with a light yellow to pinkish color, the outer mantle being composed of triangular latex-filled cells staining with sulpho-vanillin, and emanating hyphae without clamps. C. tucumanensis ECM exhibit a white (silvery) to yellowish brown colored mantle covered with soil particles, and emanating hyphae with clamps.
