The roots of Gaultheria poeppiggi (Ericaceae) were examined for fungal symbiont colonization. Typical structures of ericoid mycorrhizas (hyphae and intracellular coil hyphae complexes), dark septate fungal endophytes (hyphae and sclerotia), and arbuscular mycorrhizas (hyphae, coils, vesicles and arbuscules) were found in the roots of all the individuals examined. The evolutionary derived position of Gaultheria within the Ericales, may suggest a recent acquisition of the ability to form arbuscular mycorrhizas by G poeppiggi rather than having retained it from ancestral lines.
