STUDIES IN THE AGARICALES OF NEW-ZEALAND - NEW SPECIES, NEW RECORDS AND RENAMED SPECIES OF PLEUROTUS (PLEUROTACEAE)

Six species of Pleurotus (Fr.) P.Kumm. are recognised. Descriptions ar e given for P. purpureoolivaceus comb. nov. (= P, rattenburyi), P. vel atus sp. nov. and P. parsonsii. Three new records, P. australis, P. op untiae and P. pulmonarius, are described from New Zealand material, an d cultural characters and mating systems are reported. An anamorphic s tage, Antromycopsis sp., is described for P. purpureoolivaceus. Interc ompatibility tests confirm that P. australis, P. opuntiae, P. ostreatu s (extra-limital), P. pulmonarius and P. purpureo-olivaceus are geneti cally inter-incompatible. Lentinellus crawfordii, previously recombine d as Pleurotus crawfordii, is reinstated, and Resupinatus crawfordii i s recombined as Panellus crawfordii.
