The skin is at least 1mm thick….

As shown in the last photo. According to Arora, many Scleroderma have peridiums of 1-3mm. This one is also young.

If I happen to come across this guy again, I’ll show you photos of a more mature specimen. I knew it was Scleroderma the second I saw it. Feeling it’s consistency confirmed this to me. “As hard as a superball”.

Feel free to vote Calvatia or whatever, if that is what you think it might be….

Also, in 79952 we had the same argument about the same genus in the same EXACT location, within 3 feet. I walked back up there to prove it you. I am not going to do that this time, since I know what Scleroderma look and feel like.

I’m moving on.

you provided photos of fungi with thick skin. There is none here.

I don’t feel the need to keep going through this with you.

Scleroderma means “thick skin”. Where is it?

As if?

of the many collections I’ve submitted to Dr. James Trappe for identification. They were often identified as “tuberculate mycorrhizae”. That was Jim’s tactful suggestion the collection was too immature for positive identification.

Been there, done that….

I’ve went through proving this Scleroderma to you before, at this EXACT location. Same thin-skinned argument….

Thank you for your input, but this time I’m not walking back up there to prove it to you.

Respectfully disagree, Tim.

The thick peridium typical of Scleroderma is missing here. True, it could be one of the thin-skinned varieties, but even those should have a peridium of 2mm or more.

Gleba very young. I doubt there are mature spores.

The upper exterior looks as if it were damaged while younger, and has healed itself: a feature also similar to Calvatia. It is possible to slice the upper portion of Calvatia several times while it is maturing, taking a nice steak home each time. And each time, the surface will heal itself.
