Re:Helvella sp. ?
The second species may be Helvella juniperi. The macroscopical appearance is similar to Helvella lacunosa, but normally the ribs of the stipe have blunt edges. The spores longer than 20-21 microns and in good proportion subcylindrical are also typical. You should control the ectal excipulum in a thin section. The ectal excipulum in H. juniperi is thick about 200 microns and made up of chains of inflate cells; in H. lacunosa is thinner (80-120) and with the terminal cells +- clavate and bigger than others.
