Abstract
Several fungi were isolated from ericoid mycorrhizal roots of Calluna vulgaris plants growing on natural heatherlands in northern Italy. Many mycorrhizal fungal isolates did not form reproductive structures in our culture conditions, whereas others could be identified as belonging to the species Oidiodendron rnaius. Molecular analysis of both sterile and conidia-forming fungal isolates with PCR-RAPD techniques has revealed that: 1) the root apparatus of a single plant can form mycorrhizae at the same time with fungi belonging to different species; 2) even in the same root apparatus, a high genetic polymorphism exists among mycorrhizal fungi belonging to the same species; 3) individual fungal isolates showing the same DNA fingerprint were found to be associated with the roots of plants growing at some distance from each other.
