Notes

Pleurotus is an easy genus to identify, if you look at the spores. A number of genera (Lentinus, Lentinellus, Hypsizygous and Panellus) superficially resemble Pleurotus, but, of this group only Pleurotus has inamyloid, cylindric shaped spores. The reader is referred to Largent and Baroni (1988) for a good description of the differences in these genera.
