I did some "gorilla spawning" earlier this year with some grain that was colonized with morel mycellium. I started the spawn from wild spores found in the region (southern Ontario). A friend has 100 acres of mixed land; pasture leased to farmer next door, some hay, forest & low wet areas. There are some very old apple trees allong the pasture, I scattered the spawn under these trees. There may already be morels on the property, but they've only owned it for a year & no luck this past springs hunting.
I also have some logs I innoculated with shitake plugs. There are commercial growers in the region, It would be interesting to see if some wild specimens start showing up.
I guess I've explained my yes vote, although I do wonder about the effects with the comercially grown(& my hobby) imports.
