Recognized by sight: Reason being, one of the supposed sequencers of the DNA or whatever recently scoffed at my using Mitrophora for the genus name. He says this is Morchella. I don’t know who is right about morels anymore. It’d be nice to see that new paper soon but I’m told it won’t be public for some time.

I’m staying there. I will say though that voting not likely that this is a Morchella species is discerning. Because, it is a Morchella.

I would imagine it’s a similar taxonomic situation to the name Morchella esculenta, in that it was originally formally described in Europe, no one has formally published new names, and we’re on another continent trying to guess what to call our mushrooms. The DNA evidence says that semi-free morels are Morchella, but the taxonomy lags behind. North American semi-free morels probably won’t be called “semilibera” once it’s all said and done, either. Call it the old incorrect name (Mitrophora semilibera) or call it the correct but less precise name (Morchella sp.). Either way you can leave some notes to include an informal name, such as “eastern North American semi-free morel”.

From what I understand is that Mitrophora semilibera (a European species) should be called Morchella semilibera. But from what I hear, none of the European Morchella species occur in the US according to the DNA results. Hell, I don’t know…

What do you know about this? Why Mitrophora semilibera? I was told that nobody uses that genus name anymore. Just confused about this all.

I welcome the DNA overlords too. Without them we’d all be debating and arguing endlessly over a great many things. Thank you for the info and link.

Their DNA evidence has the half-free morels situated within the “black”/“elata” clade, making them as much a Morchella as Morchella elata is, in theory. They identify one species each from western N.A., eastern N.A, and Europe (of the morels they analyzed). It’s changing fast — I, for one, welcome our new DNA overlords. http://pubget.com/paper/20888422
