Found some Agaricus in the Botanic Gardens this morning. They stain yellow, so are in the Section Xanthodermatei, but they are not A. xanthodermus. I doubt they will get a full identification because Agaricus in Australia are rather poorly studied. But anything that stains yellow is off the eating list.

This lot were under some sort of conifer. The oak leaves in the picture are from other trees nearby.

And this lot were under a pin oak.

I see your continuing expertise with fungi is expanding. Agaricus – I have never seen one of those in the wild, that I was alert to. My knowledge of fungi is limited. When I was clearing a site of animals before a bulldozer came and did the job, I found logs with all types of fungi on them, so I carried them across the road which wasn’t going to be developed. I didn’t know what types they were, but I considered not all the botanical species in that area hasn’t been catalogued. So potentially I was saving something important. But I will never know.
