A big undertaking now that all the keys have been laid out! I’m looking forward to seeing the new BAMS page for the Morchella coming soon!

What a great resource for those still using “black morel,” “blond morel,” and “grays” as a general key(myself included after giving up so many times with cross characteristics of so many Morchella collections in the past).

Thanks again Deb-



I am diving into our western morels these days …

and both habitat and red staining indicates tridentina (new name for former frustrata).

Beug does mention the red staining in his description of frustrata, now tridentina.

does rufobrunnea even occur in natural settings???

I though that it was exclusively a wood chip dweller.

I have seen this sort of red staining on quite a few market morels, but frankly, never thought to ID them to species…some of the blondes will also stain red over time.

I have seen it a couple times-

Before too and never thought to question it… Thought why not see if Darvin or other experts may have some insight into a Hypomyces with Morchella spp. May just end up to be part of this strains growth habit. Thought I’d put it out there either way though…

Dont think

this is a hypomyces. I have this often on many of my morels. Never thought to question what it was however….
