Excavating a more mature specimen revealed its bitorquity.

Perhaps my knife featured residual Pisolithus gunk and artificially stained these mushrooms, perhaps there actually was some legitimate yellow discoloration especially right under the cap cuticle.

I will investigate more carefully if/when I find more.

These smell BAD

Very clear yellow staining

The yellow in the first pic isn’t an artifact. The yellow didn’t fade to red as I’ve seen in bernardii
