Pleurotus purpureoolivaceus

Pleurotus purpureo-olivaceus is a gilled fungus native to Australia and New Zealand. It is found on dead wood of Nothofagus trees. Although morphologically similar to some other Pleurotus fungi, it has been shown to be a distinct species incapable of cross-breeding and phylogenetically removed from other species of Pleurotus.

Stipes are lateral and white to yellow....read more on Wikipedia.
