| Resumo: |
Twenty-nine isolates of the ectomycorrhiza fungus Pisolithus sp. from different geographical and host origins were tested for their ability to form ectomycorrhizae on Eucalyptus grandis and E. urophylla seedlings under greenhouse conditions. The ectomycorrhiza-forming capacity of isolates varied greatly from one eucalypt species to the other. All isolates from Eucalyptus, nine from Pinus spp. and two isolates from unknown hosts formed mycorrhizae with E. grandis and E. urophylla. Root colonization rates varied from 0 to 5.2 % for all Pinus isolates and those from unknown hosts. Colonization rates for these isolates were lower than those observed for Eucalyptus isolates (0.8 to 89.4 %). Three isolates from unknown hosts formed mycorrhizae with neither Eucalyptus species. The main characteristic for distinguishing Pinus from Eucalyptus isolates was mantle color. These data corroborate previous results obtained in our laboratory indicating that the isolates tested represent at least two distinct different species within the genus Pisolithus.
