The genus Pleurotus in Argentina: mating tests

Lechner, B. E., J. E. Wright & E. Albertó (2005): The genus Pleurotus in Argentina: mating tests.

Sydowia 57 (2): 233-245.

In order to study the sexual compatibility, monosporic cultures from 32 strains belonging to four out of the six Pleurotus species recorded from Argentina were obtained. All tested species have a heterothallic multifactorial tetrapolar mating system. P. pulmonarius and P. ostreatus could be separated by interspecific crossings only. Our mating tests confirm the synonymy of P. smithii with P. cystidiosus. Compatibility tests confirm that in Argentina there are, so far, 5 Pleurotus species, namely P. albidus, P. cystidiosus, P. djamor, P. ostreatus and P. pulmonarius.
