Thanks for the i.d. help Tuberale, I'm in the western Va. mountains. I didn't know there were that many varieties around here, they're all deliciosa to me, lol. I'd have to say the mountain blacks and greys are tastier than the lower elevation and larger yellows imo. How has your season been? I see you're in one of the best areas for mushrooms.
Thanks for the location. I don't think you have any danger of my interloping on your picking sites.<G>
A lot of people don't know there are different types of morels. Neither do a lot of mycologists. Nancy Smith Weber is one of the experts in the area. I suppose I am too, as I have cultivated morels since 1985. One of the keys to identification of species being able to cultivate them.
Locally the fire morel (Morchella angusticeps) is the most common and probably the easiest to grow. It is a devastation fungus, being the first to fruit after forest devastation events. Within a week of Mt. St. Helens eruption in 1980, it was found growing in the ash. It is one of the fastest growing fungi in the world. It can cross a 3.5" Petri dish in a day at 77 degrees F., and because of that can fruit 30-150 yards from where it is started growing at.
Growing it outside has many advantages. Putting any morel pieces or residue into a compost pile is an excellent idea, as that appears to be the preferred food source (substrate). I have also grown morels on freshly-chipped green Douglas-fir branches. Wheat straw is another known substrate.
M. deliciosa should be mostly conical with white ridges.
You are right about Oregon being among the choice spots for morels. I have personally seen specimens which measured 17-22 inches tall, but weighed less than 4 ounces. On the other hand, I have also seen Morchella caespitosa (Clustered morel) nearly a foot tall in clumps that weighed over 1 pound. Sad thing (but someone's gotta find 'em).
Cultivators in OR and WA are starting to see surprising results. At least some morel species, such as M. esculenta and Oregon White oak, appear to form mycorrhizal relationships (mutually beneficial with growing trees). Older Black cottonwood can also have some dramatic mycorrhizal fruitings, which is where those very tall morels came from.
