I look forward to that paper.

yes … long ago (Jan. 2015).

There were a very few Kuo names retained; all of those which got simu-names went to Clowez (to the victor go the spoils). Sadly, Morchella californica, my morel, was subsumed into the genetically and morphologically identical M. americana. Reasonably, enough, since it has a ridiculously broad range across all of the US and which now includes Europe, through introductions!

If you go to Kuo’s website, though, he continues to use HIS names, in all cases. But, they are wrong, for the most part.

AS a footnote to this story, Clowez attempted to work with Kuo on several occasions but was rebuffed. Clowez persisted, published his study first, after much work and international collaboration, and the names that we now use are mostly due to his efforts. M. prava, which is still a good species concept and latin name, was not examined by Clowez. You will need to see Kuo’s work for that description. What you show here could still be either M. americana or M. prava, baring further micro and DNA analysis. Without a specimen, we’ll probably never know for sure.

For a list of which latin morel names were kept and which were rejected, go to Table 1 in the definitive French morel genetics paper. This version of that paper, linked to below, was released in advance of its March/April publication in Mycologia, and is much easier to view than the one linked to above. Scroll down to see Table 1, and the graphic diagram of the world occurence of these morel species.


Has Clowez supported any of his names with DNA evidence yet?
