Medium sized morel, commonly called a "Black Morel". These were found under Tulip trees (Liriodendron tulipifera).The head is yellowish-brown with many pits created by vertical and horizontal ridges. The stem is whitish with tiny granules of the same color. Like all true morels, it is hollow from top to bottom.
Morchella taxonomy has been newly redefined, so the official name is new.
You can search far and wide, but what you need might just be in your own backyard! :)
Under poplars in North Park, found 3, 2 dried up & this one, we need a downpore.
