Confirmation of identity ofPleurotus abalonus withPleurotus cystidiosus by scanning electron microscopy of anamorphs

A species ofPleurotus cultivated on a commercial scale in Taiwan was described asP. abalonus Han, Chen etCheng. However, both cultures and fruiting bodies, when compared with those ofP. cystidiosus O.K. Miller, were found to be identical. Since in cultures of these two species a very rare type of anamorphs — the coremia—appears, we studied this phenomenon by scanning electron microscopy and found no difference in morphogenesis of anamorphs of the organisms kept under the two names. This contributes to the opinion thatP.abalonus is not a new species and it should be considered asP.cystidiosus. Similar vague examples in thePleurotus ostreatus complex that call for an application of a new approach in identification are pointed out.
