High Contrast, with Squat & Grooved Pileus?

“Helvella dryophila looks similar to H. vespertina, but the contrast in color between pileus and stipe is striking; the pileus is very dark and squat and rounded with distinct well defined grooves when young” p 1281 [Nguyen 2013]

I’m thinking these samples qualify on all counts, but have seen more convincing samples of “well defined grooves”. I’d give a few points toward H. dryophila.

there were Black Oaks and possibly other oaks in the area.
Could go either way but since the authors of the new species names indicate H. dryophila is more of a spring entity, I’ll lean in favor of it.

black oak not in leaf …

I also found a Helvella under both pine and leafless black oak in the Sierra recently. this year, “timing” of fruiting is not a slam dunk, and when both trees are present, only DNA will tell you its name.

Were the black oaks leafed out yet? When I was in the area a the week before the observations and didn’t see any oak leaves out. Not sure it that would even make a difference.
