Observation 164551: Morchella Dill. ex Pers.

These were growing alongside MO#164542.
Although I was able to get spore prints from those fruit-bodies, these did not drop any spores. Under the microscope, I was not able to find any spores and the asci all appeared to be empty. Example = second photo.
My very tentative hypothesis is that these are the same species but the whitish-pinkish colors are due to the fact that they are sterile(?).


Asci in Congo red @ 1000X.

young(but legal) and smaller morels in that same area which were fully developed.

They are really young

but maybe they were never going to produce spores.
I’d say your sterility/color hypothesis is a good one.
Nice observation!
