Sounds prety stupid to me , illegal and protected......but.... if they grew naturaly they are not illegal = if the police cant prove that you have cultivated them they cant prosecute you . = dont get caught with bags of spawn or spores . Do the work , get rid of the evidence , put the spawn out in the wild , wait till they flower and pick "wild" mushrooms . Its best to start in mid winter to grow spawn and to put it out at the start of september . As you say they dont like to be in a sunny place , but sometimes they dont come in the first year , sometimes they come in the 2nd year , so leave them alone and watch and wait. There is no chance that they will come now untill about October because there has been to much frost . If you grow spawn in a bag you can split them and grow more bags , with P.Cyanescens you dont need to take much care about sterility once you have spawn growing . Just dont let the chips get to wet and keep them away from spores that grow on wood . The more spawn you have the more places you can try to put them out . They dont like it to wet or to dark , they like it when they get ocasional sun = try in the woods under / around oak and fir trees . With a hand full you can inoculate a patch of shreded wood chips . I have put chips over grown with mycel in a plant pot on a 5th floor balkony unprotected and they flowered for 3 years . P.Azurescens are in my experience much harder to grow than P.Cyanescens . If you ask me questions in English i will tell you what you need to know . If you send me a PM maybe i can tell you where to get some P.Cy spores .
