Notes: Growing in grass near the street. See notes on pictures; this could also be G. brunnea, I think, but it looks quite different. Other similar Gyromitras not found in this area.

there’s a lot of confusion regarding some of the Gyromitras. Some tend to have sharp seams on the cap, and others tend to show softer folds. I think that Kuo has it right. Brunnea is the one with sharp seams (pointed peaks), whereas caroliniana, gigas, and korfii (if korfii is actually different from gigas) show smoother folds. The giveaway with caroliniana is the red cap color, like the one seen here.
At least it seems :-) to make it less complicated to tell brunnea and caroliniana apart.
I agree, it would seem (ha! get it?) that “seam” as used for G. brunnea has a different meaning than when applied to G. caroliniana. Even so, that didn’t stop the Peterson field guide from using the presence of “seams” like the one I show here as a diagnostic feature for G. caroliniana. Although others, like Kuo seem to use the term to refer to the sharp ridges on G. brunnea. I think that Peterson is trying to distinguish caroliniana from gigas or fastigiata?
