Thanks Rainbow and Applestar!
I have seen an article where a guy built mushroom boxes outside, and started mushrooms. A long time went by, nothing at all. Then he had a leaky garden hose, and mushrooms popped up, everywhere except in the box he had so carefully prepared. I can't remember the details so I went looking for it. I had no luck finding it, maybe I have it in notes somewhere, I will look closer. But, and this is a big BUT, I found a very interesting site... Mushroom Appreciation.
I think, that I got my answer in this paragraph from them...
To create this solution you'll need some wild morels. They should be mature, although not mushy or rotting. A few mushrooms per gallon of water will be sufficient.
Follow these easy steps:
Start with some clean, non-chlorinated water in a food-safe container.
Add a pinch of salt and about a tablespoon of molasses to the water and stir. You don't need much of each. The salt is to inhibit bacterial growth; the molasses is to provide sugars for germinating spores.
Add mushrooms and let the mixture sit covered for 1 to 2 days in a temperate place. Any longer than that and you risk bacterial contamination.
After you strain and remove the mushrooms you'll have a liquid with millions of spores!
This spore liquid can be spread over a prepared bed as described above (sandy soil with peat moss, ashes, and wood chips). It can also be spread in other known morel habitats, such as at the base of dying elm trees. Feel free to experiment with your slurries.
This process is easy, but the downside is that it can be unreliable. A spore slurry is not as far along in the life cycle as mycelia in spawn, so the odds of success aren't as good.
However this is one of the cheapest and easiest ways of growing morel mushrooms, so why not give it a try?
On this site the lady talks about all kinds of mushroom info and even about grow kits, and tree growing them, etc.
It is not a forum, I don't know if they sell stuff or not, but it was very informative...
Obviously, if I soak the morels for a couple days, I don't want to eat them!
