I normally grow things like pioppino, lions mane and oysters, this is my first time growing a polypore. It took a long time, many months haha. I think this was inoculated back in november and I just got around to fruiting a few weeks ago. Lots of spore samples to put under the microscope, let me tell you.
They look almost identical to each other but I believe G. tsugae tends to favour conifer, I grew this on hardwood.
Okay. You are correct, tsugae prefers hemlock and will grow on other conifers.
