Research and MO have progressed since Johannes Harnisch’s 2010 Comment below. See the references at the Morchella MO Name page. Among other things:
- Morchella angusticeps is confirmed in eastern North America
- If you’re unsure which “black” morel you have, you can use Morchella elata clade or Morchella sect. Distantes.
- There are at least 11 North American species in that clade/section:
After you have finished reeding all that
and find out that M. elata is not even verified in North America,
you will also discover that apparently there is actually 5 different black morels in NA (North America),
you will be told that the only scientific black Morel name in NA is M. angusticeps (I don’t know how this matches up with the 3rd Paragraph on this page http://www.mushroomexpert.com/morchella_black.html which seems to be saying there are defiantly other verified black morels [5 in fact] found in NA, may be some one will explain it? )
then to add to the confusion, This page
you will discover that M. angusticeps is possibly in correct and that name should be abandoned!
I don’t know what every ones consensus is but I would propose calling them by either a non-Latin name such as Black Morel .
or just sticking with the original Morchella elata and then some one just has to go through all the obs when/if that name is rejected in NA and change them to the future correct name, ?
