S ummary The addition of a small quantity of glucose (0.5 g 1 −1 ) to the culture medium enhanced mycorrhiza formation on Vaccinium angustifolium Ait. and V. corymbosum L. with Pezizella ericae Read in vitro . Under these conditions, 15 isolates of ericoid mycorrhizal fungi obtained from diverse hosts and habitats demonstrated different abilities to colonize the root system of the two species of Vaccinium . Moreover, the addition of activated charcoal especially in presence of glucose or pectin greatly stimulated ericoid mycorrhiza formation by P. ericae on V. angustifolium . The possibility that active charcoal adsorbs toxic compounds from the rhizosphere is discussed.
