Description/Abstract A study was initiated to assess the potential of Pisolithus tinctorius as an ectomycorrhizal associate of containerized sweet birch (Betula lenta) and European alder (Alnus glutinosa) seedlings and to determine the effect of this fungal symbiont on seedling growth.^In a test of sweet birch and European alder grown in Leach tubes, P. tinctorius formed abundant ectomycorrhizae on sweet birch when introduced via a vegetative mycelial inoculum.^Cenococcum geophilum, originating from sclerotia present in the potting medium, and Thelephora terrestris, introduced via wind-borne propagules, formed ectomycorrhizae on the sweet birch seedlings inoculated with P. tinctorius and on the sweet birch control seedlings.^C. geophilum also formed ectomycorrhizae on the inoculated and control European alder seedlings, but an inoculation with P. tinctorius did not result in the formation of P. tinctorius ectomycorrhizae on this host.^Sweet birch seedlings infected with P. tinctorius had a greater dry weight, height, root collar diameter, and volume and a lower shoot/root ratio than the sweet birch control seedlings, and European alder seedlings with abundant C. geophilum ectomycorrhizae exhibited a similar improvement in growth in comparison with European alder with lesser C. geophilum infections.^The inoculation of containerized sweet birch and European alder seedlings in the nursery with the appropriate ectomycorrhizal symbiont may facilitate the establishment of these species on harsh sites such as surface mine spoils.^57 references, 3 tables.
