The basidiomycete Suillus luteus (L. ex. Fr.) Gray was identified as mycorrhizal symbiont in Pinus elliottii Engelm. var. e/liottii root system. The mycorrhizae were typically ectotrophic, with branched morphology in the early stages and tuberculate at matunty. The ectomycorrhizae had a hyphal mantle 3.59 - 33.66 µm thick as long as in the tuberculate type, in, which were found up to eleven root tips ins1de one tubercule. The Hartig net penetrated the outer three epiderma! cells with mycelial penetration in the intercelular space of 0.29 - 0. 76 µm. ln vitro isolates obtained in Modified Melin Norkrans (MMN) from basidiocarps and mycorrhizae presented the sarne cultural characteristics. Mycorrhizae were axenically synthesized by inoculation of these isolates in Pinus elliottii var. elliottii in aseptic conditions.
