genus Pleurotus in Argentina

Macro- and micromorphological characters of specimens of the genus Pleurotus (Fr.) P. Kumm. in Argentina obtained in the field and from different national herbaria were analyzed. Cultivation techniques were used to obtain basidiomata, allowing for a macro- and micromorphological study of fresh developing fruit bodies. We concluded that in Argentina there are, so far, six species, namely P. albidus, P. cystidiosus, P. ostreatus, P. pulmonarius, P. rickii and P. djamor, the latter with three varieties: var. djamor, var. cyathiformis and var. roseus.
