Kuenzler hedgehog cactus
New Perspective: I am not comfortable with fungi at all. How would I distinguish Morchella prava (https://www.inaturalist.org/taxa/629239-Morchella-prava) from Morchella americana (https://www.inaturalist.org/observations/214405562)? Is it possible from these images? I can see that this observation is of an individual with more convoluted, less vertical, ridge structure. The specimen was found in a mixed forest zone along a creek at about 7200'. The stream floods with the monsoons so the soil is quite sandy. Ponderosa Pine, Gambel Oak, and willows.
Original Post: Possibly Gyromitra montana or Gyromitra esculenta? (But ridges are much deeper and are blistered at the top.) Similar to Morchella steppicola which is a European species. Note the blistered ridges, but stem does not have flutes in the individual shown here.
