Also of note from the more recent Loizides et al 2015: “Bayesian and maximum likelihood phylogenetic inference based on ITS region suggested that M. tridentina, M. elatoides, M. quercus-ilicis, and M. frustrata should be considered synonyms (Fig. 1), with the first being the prioritary epithet. This
was further confirmed with complementary tef1 and rpb2 sequencing
(Table 2). Intraspecific variability was extremely low, with only 7/575 positions showing scattered point mutations, many of them insertions at poly-nucleotide regions. A single putatively apomorphic mutation was observed in the
ITS region of the American lineage (M. frustrata), but tef1
(531/531) and rpb2 (551/551 to 550/551) were almost identical
between M. frustrata and the European collections.”

Richard (Bellanger) et al 2015 which found that Mel-2 of O’Donnell et al 2011 = M. frustrata of Kuo et al 2012 =M17/JQ723020 of Du et al 2012 = M. tridentina. M17 is the reference sequence for taxon determined by multilocus analysis. So this obs is M. tridentina judging by her comments below and by the current literature. If you have the sequence it would be interesting to blast it with the reference sequence JQ723020.

On 2018-02-02, Prof. Mary Berbee wrote: “We checked the ITS sequences of both specimens in F28215 Observation 139454: Morchella snyderi M. Kuo & Methven.”
“The sequences are the same in both. They’re closer to European Morchella tridentina than to Morchella snyderi.”

“Kuo et al. 2012 erected a new N. American species, Morchella frustrata, that Bellanger et al, 2015 synonymized under M. tridentina. It looks as if N. Americans are following Bellanger et al and so I will too, but with misgivings. The North American M. frustrata that corresponds to the type is about 1% different from M. tridentina. Your specimen sequences match M. frustrata.”

it is just the other way around.
