So, I just searched 'mushroom spawn' on Google, in the 'shopping' mode, and turned up this.
There are evidences of 'mushroom logs', wherein one purchased the already spored wooden log and, presumably, follow their directions upon receipt of the log.
However...The spawn seems to be often sold as 'spored dowel plugs' that one inserts in some wooden source. This seems to me would avoid much of the associated shipping cost attendant to shipping a wooden log to wherever. Just a thought.
Then, the array of choices! The oyster mushrooms appeal to me, but I could go with criminis, too. No shiitake; I've been there and they didn't impress me much.
The inclusion of an aminita muscaria photo as advertising copy seems a mite...troublesome.
My curiosity remains piqued by the mushrooms on a plastic bucket scene.
And, I have a basement! Warranted, it presently reeks of catbox, but....hey.
Okay....I just got back from my pre-feast run to the farmers market. I went for decent apples (not otherwise available in normal grocery outlets) and I found blackberry honey, botanical gin, and chestnut fungi. The later was from a vendor selling the most eye-catching bouquets of mixed fungi. The most notable were the large pink oyster mushrooms that looked like gorgeous exotic flowers in full bloom. Me? I went for the chestnut mushrooms, which look like they'll be an aesthetic addition to my green bean casserole.
Of course, with this thread in the back of my mind, I pumped the vendor after he told me he started as a hobby and and has an entire greenhouse dedicated to various strains of fungi...he must have had eight or ten strains way different than the usual Crimini or button mushrooms one finds in the typical market. He said it was really quite easy, but noted that the fungi have fairly demanding environmental constraints which makes them a mite....cranky.
