Mushroom manure has not been used and hard to come by.
Mushroom compost has not been used and less difficult.
If you want the manure you can always try to make your own, but collecting the ingredients is a chore..
.......Mushroom manure/compost is a totally organic rich, dark, moist mixture of wheat straw, peat moss, cottonseed meal, gypsum, lime, and chicken litter. This combination of ingredients is used in commercial mushroom farms to grow mushrooms. These materials are composted for many weeks and then placed into a huge room where it is completely sterilized and then the mushroom growing cycle begins. Strangely enough, mushrooms will only grow in this mixture for a very short time, usually 18 to 20 days. At this time the compost has to be removed and a brand new batch will already have been prepared for the next crop.
This recipe does not inclue sawdust and I've been told that is often a part of the recipe.
We have a local sand and gravel that gets the used mush. compost, yes it is rich dark looking dirt...Almost like commercial bagged topsoil, more black.
It is the blackest, darkest dirt they sell. At $80/yd compared to $30/td for top soil, I've not been able to bring myself to invest in stuff I can put together for next to nothing.
Good luck and good gardening
