Some precisions

I suggested the name G. brunnea due to the date (June), but if it is not the real date of gathering, G. infula could match. In Europe, G. infula grows often on dead wood, generally on Fagus, in mixed woods (Fagus and Abies/Picea).
Don’t forget there exists also G. ambigua which looks like a small infula and grows in summer but in boreal areas.
Of course, spores are very different between G. infula and G. brunnea, so in doubt, it is easy to control!

has been a mess for many years. I don’t think Gyromitra brunnea occurs in Montana or if it does,it is very rare. Gyromitra infula is usally an autumn species and is often found on wood.

G. infula grows only in late summer or autumn. Gyromitra brunnea grows in spring. Gyromitra fastigiata, name used in Europe, could be a synonym
