Last spring I found on the internet classifieds a stable owner in my area who was giving away free horse manure. So I went over there with my trailer and we filled it to the brim.
Back home I mixed the manure into the soil of my garden with a tiller. I also kept a mound of manure under the shade.
I didn't expect much of it though. I needed the manure for my vegetables anyway, so I kind of forgot about the possibility of Panaeolus subbalteatus appearing.
A month later, after 3 days of rain, the subbs started to sprout all over my garden and on the mound. Since then, I've been watering my garden every day or so, and the subbs keep on popping.
I pick them almost on a daily basis.
So far, after 3 weeks, I've picked about 1/2 pound of subbs (225 g fresh, 22 g dried).
I can't believe how easy it is once the initial work in spring is completed.
All you have to do is pick them while you tend to your garden.
You will find them growing mainly under leaf cover and at the base of vegetables.
See pics below.
So why hunt for subbs when you can bring them to you? No driving around, trespassing, etc.
Sodded lawns do not seem to grow P. subbalteatus where I live. I've scanned a lot of them and the only mushroom I found growing there was Panaeolus foenisecii.
Anyway, I don't know if I got lucky or not, but for me it worked very well. I didn't have to pasteurize or inoculate the substrate. The manure was already containing P. subbalteatus mycelium and/or spores.
So I just wanted to share my experience. If you have a garden or an vacant spot in your backyard, and have access to horse manure, then this may also work for you.
The horse dung/manure was aged for 1 year the guy told me. It was pure manure (no straw, woodshavings, etc.) and had a brownish color. You could still see the remnants of road apples in it, though it didn't smelled very much, more like compost or humus than dung.
I got later some different horse manure, which was very well decomposed. It looked more like a mix of soil and wood shavings. But nothing has grown from it though (yet?). I made a concentrated spore solution from spore prints and watered the manure pile with it. I also mixed in some dry pelleted mycelium of Agaricus bisporus (common table mushroom). We'll see if anything grows in that pile later this summer.

P. subbalteatus, fennel and celeri.
P. subbalteatus and carrots.
Subbs and lettuce.
What about a tasty Subb salad?
(subbs with paler caps)
Growing in celeri.
Nice view of mixture of manure and soil.
Slight bluing of the cap umbo.
Large specimen with mycelium at the base.
That's about as big as they can get.
