While lots of fungi are very small, in some cases too small to see, today’s spotlight mushroom is hard to miss when you come across it. Often mistaken for a volleyball lost in a field, the Giant Puffball (Calvatia gigantea) is aptly named—it’s a large, usually round, all-white fruiting body often found in fields, meadows, yards, and woodland areas. I found my first Giant Puffballs this year in early November, which is a littler later than what most guides would suggest (September-October). They were located in a kind of border area between a wooded zone and a landscaped yard. One of them was being choked by vinca—this one was too mature to be eaten (see my tip guide below for how I knew that).
Luckily, the disappointment didn’t last long as I soon spotted two other perfect volleyballs nearby! It isn’t uncommon to find Puffballs living in communities like this.
Tips for Safely Harvesting Giant Puffballs
- It is safer to harvest volleyball-size Puffballs than smaller ones. Some smaller ones are fine, but there is a higher chance of misidentification in those cases.
- They are always found on the ground.
- The texture of the Puffball should be smooth, perhaps leather-like, and perhaps with small “craters.”
- There should be NO STEM and NO GILLS.
- When you cut open the mushroom, the color should be solid white all the way through. The texture should be something like tofu. If you see any colors besides white (like yellow or brown or green), don’t eat it. If the texture is mushy, don’t eat it. If it smells really funky, don’t eat it!
It isn’t exactly known whether this mushroom is mycorrhizal (in a complex relationship with plant roots) or can simply spread its spores anywhere to reproduce, but what we do know is that it isn’t easy to cultivate like some other mushrooms. I would suggest simply noting where you found a Puffball and returning there the following year to harvest again.
Eating Puffballs: A Recipe for Pizza!
There are as many ways to prepare Puffballs as there are ways to prepare meat or tofu. One idea I’ve heard about from forager friends that I decided to try this time is Puffball Pizza. It turned out great! I’ll share with you my basic recipe below.
The next time you find the spectacular lost volleyball fungi poking out from the ground, go ahead and get excited! You really can make a feast with this mushroom, and food security and deliciousness are definitely things to get excited about. For me, there’s a thrill and feeling of connectedness when I am able to forage for wild food. Luckily, puffballs can have trillions of reproductive spores, so as long as one of them is left on the ground to reach maturity, the spores will ensure future mushroom friends, fruiting bodies, and hopefully plenty of Puffball pizzas to come.
Note that if you do not have personal experience mushroom foraging, it is suggested to obtain a positive ID from your local mycologists or experts. Some wild mushrooms are poisonous and it is your responsibility to identify wild food before ingesting.
