Two methods were compared intending to distinguish between the clones of the root‐rot fungus Armillaria obscura (syn. Armillaria ostoyae ) in nature: one based on the pairing of the diploid isolates in pure culture, the other using the incompatibility alleles as genetic markers. As A. obscura fruits easily in vitro, both methods could be used for any type of diploid isolate whatever its origin. The two methods were quite superposable and defined the same clones. Artificial diploids issuing from the same fruitbody and isogenic for the incompatibility alleles appeared to belong to the same clone in pairing tests.
