anyone done mushrooms?

Got a packet of the white pellets (bit like pills) which it says you place in straw or horse manure and just stand back. Should be put in a coolish, dark place.
I filled a couple of wooden trays, one with potting compost and wood chippings and the other with straw, and put them in my anderson shelter on the plot. If you kept them moist, you could see the spiders web-like filaments spreading out from the pellets, but in this weather, I found I was misting them with a spray bottle all the time just to keep them moist, so I gave up.
I'm assuming you need a moist environment and probably cooler than anyone has just now, so I've stopped bothering, intending to start up again in the autumn, which is traditional mushroom time anyway.
I'll just have to see if I need to 're-seed' or whether the ones I've already planted will just pick up again in the right environment.

I'd give it a try, but suggest poking the seeds into the pony poo rather than just sprinkling.
