Re : Helvella
Or, maybe, that key is not so good.
You need to observe the ascus base (with or without croziers), and please show us an image of the ectal excipulum, in water.
Also the habitat helps, ecology in some Helvella is very distinctive.
However, judging on the photos, I bet:
- asci with croziers
- excipulum whith incospicuous, short-celled hairs
- vacuolar pale brownish pigment into the ectal excipulum, not distributed everywhere
- habitat under broadleaved trees.
Let me know
Regards
Mario

Re : Helvella
You have a very, very interesting Helvella, it belongs to the Leucomelaenae section... the base of the asca is type pleurorhynchous, therefore it belongs to the complex of "H. solitaria", because ribs are extending only slightly onto basal excipular surface...
