They lacked a lacunose stipe and the species is named for that character. They have a ribbed stipe (as do many Helvellas), but lack the holes into the inner chambers that Helvella lacunosa is suppose to have.
I never heard of either H. palustris or H. philonotis. What led you to these species: was it the form of the cap, the consistency of the cap (smoother than in H. lacunosa) or anything else?
Your spores lack oil drops and appear to be immature. Maybe they will get bigger.
Abbott & Currah list a European synonym for H. palustris as H. philonotis.
After the suggestion of Helvella palustris by Darv, I decided to observe the spores under the microscope. I have already uploaded some photos. The dimensions obtained:
Ascus: 200- 240 × 12-15 µm,
Spores: 12-14.5 × 8.6 – 10.4 µm,
are much lower than I expected also much lower that the dimensions of the spores of either H. lacunosa or H. palustris, presented for instance in “mushroom expert”.
Then, what can it be?
