I just stumbled on this citation for a paper that has not yet been published, apparently: Kuo M., Dewsbury D.R., O’donnell K., Rehner S.A., Moore J.D., Moncalvo J., Canfield S.A., Carter M., Stephenson S.L., Methven A., & Volk T.J. 2012. Taxonomic revision of true morels (Morchella) in Canada and the United States. Mycologia.

From the abstract: “Here we describe 19 phylogenetic species of Morchella from North America, 14 of which are new…M. importuna…”

Having the abstract but not the rest of the article is such a tease.

Cool I hope someday to find some

I beg to differ about the taxon J morchellas not being in michigan I just found a flush of over 200, in wood chips, some near the concrete edge. All had the tight pits and the "laddered’ look some w/ a darker base, No doubt in my mind, Taxon J is spreading!

Too bad these dont grow in Michigan :)

about the importuna taxon. Much appreciated :) Have you come across the crazy lamp post “coincidence” I keep coming across in urban settings down where you are in Oregon too?

Taxon J

Yup – these look exactly like the Morels I have been finding down here in Oregon. I had them ID’d as Morchella Importuna or “Taxon J”. Nice find! It’s weird how they seem to always grow wedged up against the concrete.

Thanks for the eye opener BlueCanue :) :)

Had not previously heard of this taxon before your post- greatly appreciated. Looks like taxon J to me too

Taxon J

I would guess that those are probably Taxon J as described by Kuo: Pacific Northwest wood chip morels with vertically-arranged pits. But I’ll stay out of the “morel wars” that have been going on around here recently. As far as a scientific name goes, I’m not going to argue with you.
