gosh, say it ain’t so! ;)
If you compare descriptions and photos from recent CA finds (yours and Glenn Walker’s recent post to SOMA) with the photos of the European collections from Clowez’s work (his synonym of Morchella elatoides) you can easily see the macro similarities: non-burn morels, initially gray fruit bodies, turning yellow and reddening, and with the very top of the cap split; the base a bit swollen and buttressed, but not as dramatically as in snyderi.
The French DNA paper found six different species that occurred both in Europe and the US.
Until our DNA abilities improve, and we are able to match more places on those morchella genes, this appears to be a good working knowledge.
I am fine with the conclusion of the older name of M. tridentina for these macro-identical collections. After all, some of the best myco-geneticists on both continents had a hand in this most recent work. If we can’t believe them, then who can we believe?
taking precedence over M. frustrata at this point.
Reading the recent Franck et al paper in Mycologia isn’t very convincing.
The M. tridentina is primarily a European species and all they offer is a shaky phylogenic tree with no real description or data.
Sure would like to see someone verify their claims.
