April 2006. Every year about this time, a toadstool appears in a Sydney garden; this year it is there and on the grass verge in front of the house between two large Moreton Bay figs. An identification was requested; is it Boletus (Xerocomus) pulverulentus. Its main characteristic is that it turns from bright yellow to blue, almost immediately it is cut. Later, the blue bleaches. And is it edible?

There were several interesting responses:

• As a rule, avoid boleti that bruise blue as the blue results from phenols.
• Be sure it is correctly identified before it is tasted.
• It is a Boletellus.
