While driving around in April, I noticed for the first time this year some rather large puffballs growing around the place. Here is what they looked like.
When cut open, these revealed a firm white flesh with a pleasant mushroom smell. They lacked a ‘sterile base’ which is the bit at the bottom close to the attachment point to the ground. The lizard skin pattern was also distinctive. If left undisturbed they develop a purple spore mass and break open.
All of these factors together led me to identify them as Calvatia fragilis, which was subsequently confirmed by DNA analysis (97% AJ684871).
The picture below shows the specimen torn open. There is a slight yellowing when it is bruised. It has a distinct skin.
The next picture shows another view of the surface of the puffball.
I found something similar in March 2021 after some unseasonal rain and humidity. These were a little more aged than the first ones and the skin (peridium) had become a bit more faceted but I believe it is the same fungus. This specimen turned soft overnight.
Some people say that all white puffballs in Australia are edible. This is not true as many years ago I found a massive white puffball growing next to a mulga tree in Hopetoun that had an extremely unpleasant smell. When I heated some up it caused us to evacuate the kitchen!
Calvatia fragilis is edible though and I sliced this one and fried it in butter. The taste reminded me a little of eggs.

I found a patch calvatia fragilisin the juvenile stage last month and had a go at eating them. Sliced thinly and fried in butter, they had a consistency a bit like soft tofu and fresh white bread. The taste was rather bland, just like soft tofu. Oh well, nothing to get excited about.
