Observation 45377: Helvella L.

Found this lone specimen growing on the ground in mixed woods.
The cap was about 3 cm wide.
The spores were larger than any of the usual Hevellas that are normally found in this area. They were approx. 29.0-40.0 X 19.0-25.9 microns (see photo)
Unfortunately, I let it degrade too far before looking at it more closely and had to discard it.
Wonder if anyone has see this before or maybe it belongs in another genus?

I used Congo Red and don’t recall having problems seeing oil droplets in the past.
Now I’m doubly sorry that i didn’t preserve it.

There are no known Helvella with spores like these. I don’t see any oil drops at the inside, and the oil drops are present in the entire family Helvellaceae. Maybe the stain you used make them invisible, but is also possible to investigate around Verpa.

Ron, I think you’ve got the genus right.

But I haven’t seen this species before.
