e1“bur oak seedlings were grown in three types of bioassays”
e3“the composition of EM fungi colonizing oak seedling roots was different with increased N supply such that Russula spp. (primarily Russula aff. amoenolens) were most abundant at the highest level of N supply”

Other claims from this paper (9)
- Observation Fourteen ectomycorrhizal morphotypes were found in intact soil core bioassays.
- Observation Five ectomycorrhizal morphotypes were found in resistant propagule bioassays.
- Intervention effect Increased N supply did not affect total root colonization or morphotype number of bur oak in intact soil cores in 2000 and 2001.
- Association Russula spp. were most abundant at the highest level of N supply.
- Observation Dominant Russula spp. did not colonize any roots in resistant propagule bioassays.
- Observation Dominant Russula spp. did colonize oak seedling roots from previously mycorrhizal roots.
- Association The authors suggest that N supply can influence the kinds of inoculum propagules present in this savanna.
- Observation Cortinarius, Cenococcum and Russula were abundant species in intact soil core bioassays.
- Observation Cenococcum and a Wilcoxina-like ascomycete were abundant and frequent in resistant propagule bioassays.
