Could be more than one species then Debbie.

After hearing Nancy Smith-Weber speak on the Morchellas, I am befuddled. Some may be mycorrhizal. By definition, that requires a host.

Those appearing to be M. americana without a host possible in the neighborhood, would perhaps be “true” americana. Or not. Until the host species is solved, I don’t know.

My uncle used to collect only the “blond” morel along the Santiam River in Lebanon for 50 years. He always found it with Black cottonwood, but couldn’t rule out other trees as well. As Alfred died in 2004 it is not possible to ask him now.

If I read Kuo’s work correctly, he still didn’t arrive at a name for the white morel we sometimes find in Oregon. Another quandry.

M. americana/rigida …

occurs in a wide variety of habitats and under numerous “hosts” or none at all, all across NA.

The large size, blonde coloration, and smooth stipe without a sinus where the cap connects up all indicate americana/rigida.

Nice finds!

Looks like the “blond” morel.

Possible mycorrhizal association. Need to know possible host trees, too. Black cottonwood? Oregon White oak? Douglas-fir?
