Materials on hand: junk mail, the tubes from tp rolls, spent coffee grounds, and come fall a shit ton of leaves. I have one porch that is shady, and was wondering what combo of materials on hand I should use and what variety is best for beginners. Also if possible I would like to keep my fungi alive and going over and over so a type that I don't have to rebuy would be groovy.
Oyster mushrooms (Pleurotus ostreatus) can be grown on spent espresso coffee grounds inside 5 gallon buckets in an indoor location, but make sure to design the project so you don't breathe in the spores. A friend of mine had success with this method. Oysters are one of the best species for beginners. The blewit (Lepista nuda) can be grown on a mixture of hardwood chips, bark and leaves. They also like "the duff leftover from a recently moved woodpile". I have not tried to grow this species, as I don't care for the taste. You can buy spawn for both species from Field and Forest Products (fieldforest.net). You can keep both projects going by just adding more fresh material for the mycelium to consume. Although I've grown oyster mushroom on unbleached, "unused" toilet paper rolls, you probably won't have much luck with just the empty rolls. I just use them to start fires in my woodstove. Oyster mushrooms will probably eat the glossy magazine/ newspaper stuff, but I would not eat the resulting mushrooms, as they might contain toxins. Good luck!
Wow thank you again for the speedy reply, this forum has been a great resource in cultivating my intrest and knowledge in fungi. I am saving up for mycelium running, but thanks for the help in the mean time. Two more questions if you don't mind. First should I just use coffee grounds or would multiple types of medium be ok? And can I also use the coffee filters? Thanks again.

I would guess that just using spent espresso coffee grounds would work best, as long as they are inoculated soon after expresssing to prevent contamination. I'm not sure if you might need to raise the pH by adding ground limestone (calcium carbonate) to the mix. Call your spawn supplier to insure their spawn is fresh before ordering and to get the details about growing on coffee grounds/filters. By the way, you can probably find the Paul Stametsbooks at your local library.
