I did not know about the many tree associations.

Diminutiva or sceptriformis…

can be difficult to separate from americana. I have found ones that seem quite ambiguous. For instance, obs 91469 (esculentoides = americana, virginiana = sceptriformis).

I wouldn’t put to much faith in tree association. I have collected large yellow morels (likely americana) near apple, elm, tulip poplar, white ash, white pine, sycamore, and rarely in open areas where no trees are found. I’ve also read reports of large yellows being found under maple. A friend of mine has found them in a stand of spruce.

To me the pits appear

to be vertically aligned which would point to something other than M. Americana. If so the two choices available are M. diminutiva and M. sceptriformis. Kuo separates the two based on size and trees.
