The sexual incompatibility system was investigated in the new strain Pleurotus ostreatus 'Miso'. Matings among monosporous progeny collected from fruiting bodies revealed that the new oyster mushroom is heterothallic and has a tetrapolar mating system. Single basidiospore isolates that did not have clamp connections were determined to be monokaryotic. Compatible parings of monokaryons were distinguishable macroscopically by the rapid growth and gross morphology to some extent but they were distinguished obviously by the presence of clamp connections from incompatible pairings under microscopic examination. Rarely dikaryotization was unidirectional with clamp connections only at the margin of one side of mating. In tetrapolarity of matings, four kinds of patterns, A1B1, A1B2, A2B1, and A2B2, were decided depending on compatibility tests in a parental strain with a mating factor of A1A2B1B2. The mating tests with the tester strains were performed for the detection of mating types on the rest of selected monokaryons.
