Phil, one that I let mature…

also went to purple obs 175541.

Looks like more cyathiformis around here than I thought. I still think the ones in my yard are the green spored type. If I get another one, I’ll let it got to spore.

I may have previously…

judged these types on the basis of the greenish color reported for the first non-white stage of the gleba.

I’ve got one up in my yard that I transplanted from Moon Lake.

It’s like a puffball paradise on my lawn the past two weeks. Good opportunity to learn some stuff. They’re all over our area right now!

some of these where they were found. I will double check them whenever I’m in the area. Time will tell. I’m of the opinion that cyathiformis is more global shaped than craniformis which I have found to be skull or breadloaf shaped and browning with age. I have been picking these well over thirty years and still don’t rate them highly.

I would not rate these as choice.

But they are okay if sliced, egged, breaded, and fried in oil. Or you may go one step further and layer the breaded/fried slices with mozzarella and tomato sauce between. Bake for about 30 minutes. Pretty good, but not nearly as good as Grifola prepared in the same way.

In my opinion, the only thing that reliably separates cyathiformis from craniformis is the color of the mature spore mass. Otherwise, these two are virtually identical, with the shape varying among… skull-shaped, small bread loaf, or sometimes a lot wider than tall with a smaller central stipe-like base.

I’ve got one of these two types out in my yard right now, from Moon Lake. I “transplanted” it to a spot on my lawn in hopes that it matures. For the most part, in the past I have observed the green spore-mass species.

but they are edible when the gleba is white. C. craniformis has white gleba ending in geenish yellow when old and actually looks like a skull. Both rated as choice edibles. Maybe other people know how prepare them better than I.

Phil, do you know that the spore mass…

eventually becomes purple on this?
