  abstract = {{F}resh sporocarps and root and soil samples were collected under a monospecific forest plantation of {A}cacia mangium in {D}agana in {N}orthern {S}enegal and checked for the presence of fluorescent pseudomonads. {N}o bacteria were detected except from sporocarps collected with adhering soil and hyphal strands. {P}isolithus sporocarps were dried at 30 °{C} for 2 weeks, ground, passed through a 2-mm sieve and mixed together. {T}his dry sporocarp powder ({DSP}) was used to inoculate and form mycorrhizas on {A}. mangium seedlings in a glasshouse experiment. {A}fter 3 months culture, plant growth was increased in the {DSP} treatment but no ectomycorrhizas were present on the {A}. mangium root systems; however fluorescent pseudomonads were recorded in the cultural soil. {T}he stimulatory effects on the plant growth were maintained for 6 months. {H}owever, fluorescent pseudomonads were no longer detected and 35% of the short roots were ectomycorrhizal. {S}ome of the fluorescent pseudomonad isolates detected after 3 months stimulated the radial fungal growth in axenic conditions. {T}hese observations suggest that these bacteria are closely associated with the {P}isolithus fructifications and could interact with the ectomycorrhizal symbiosis establishment},
