I grew Pleurotus and Lentinula many years ago when I first became interested in mushroom hunting (and eating)! My spawn came from Fungi Perfecti. Both were successful. Hericium was not. fyi - I read somewhere that you should let green wood rest a few months before innoculation. However, Pleurotus seems to grow on just about everything. Since my original innoculation, I've simply spread oysters around by lying them on downed wood (relatively fresh). They especially like Tulip. I live in Morgan County In the woods, so we have a lot of mushroom-ready material. Shiitake logs grow mushrooms for several years. So you get a good long harvest from them. I've never innoculated Maple, however. Good luck!!
