%X the roots of five native species of gentianaceae distributed in different environments of argentina, four belonging to gentianella and one to gentiana, were studied for fungal symbionts colonization. arbuscular mycorrhizal structures belonging to paris type (intracellular hyphae and coils) and dark septates endophytes (ds) (hyphae microesclerotia) were observed. three of the species studied were associated to both arbuscular mycorrhizas (am) and ds, only one to ds and the other only to am. root colonization by ds (hyphae and microesclerotia) and am hyphal colonization were host dependent. this is the first report of am and ds colonization for gentianella helianthemoides, g. magellanica, g. parviflora and gentiana prostrata. host and environmental influence on am and ds colonization is discussed.
