They are sometimes confused with truffles, are found epigeous (partially above the ground), and are associated with weather over 80 degrees.

One way to remember S. citrinum and S. areolatum is 1) S. citrinum has raised warts on the outside; 2) S. areolatum has an outside that looks like sun-cracked mud. That’s what areolate and areolatum mean in Latin.

These fungi are mycorrhizal, meaning the fungus lives in part off a host plant. Scleroderma are found with many different plants, trees, shrubs. They are also easy to grow, which may account for them being “everywhere” right now. Look for them anytime temperatures reach 80 degrees or more.

I usually don’t even pick them, much less eat them.

But I thought I would put a photo online because these are everywhere right now. Thanks for the warning!

the last photo is of the same species, but younger specimen.

ALL SCLERODERMAS SHOULD BE CONSIDERED POISONOUS! A 110-pound pot-bellied pig died after eating Sclerodermas in his back yard in Vancouver, Washington. Human and pig physiology are similar. A similar-sized human would probably have the save reaction. That said, I have friends who ate Scerldermas and lived to tell about it. But they spent a miserable couple of hours vomiting and getting rid of everything in their digestive systems. I would prevent anyone else from a similar experience.

on this thick-skinned puffball make it among the easiest Scleroderma to identify in hand. The warts extend several mm above the peridium (skin); the sterile basal tuft with whitish rhizomorphs are diagnostic.
