Focus on Fungi – Giant Puffball

It’s mushroom season! An interesting fungus we can see this time of year is the Giant Puffball (Calvatia). It ranges in diameter from 8 to 24 inches. That’s diameter, not circumference. When it comes to fungi, that is massive! They can easily reach the size of a soccer ball.
They are found in parks, meadows, pastures, open woods and urban areas from late August to early October.
There is no distinct cap or stem on these mushrooms – they exist as large, white globes, although they may not be perfectly round.
I’ve read that they are edible although I’ve never tasted one so I can’t substantiate that. They say the best time to harvest them for cooking is when the white exterior cracks and the white interior shows through. If you wait too long, it will turn brown and begin releasing its spores.
