prefers oaks and a warmer climate also grows underground. I think you may have nailed it.

I would not use those mushrooms. They look a bit past there prim and they probly have all kinds of critters taking up residence in them. I use fresh specimens then dry them and use them that way.

Judging by these pictures would you use these specimens? I’m sure I could cut off the moss growing on them but I have seen much fresher looking pictures of this. What do you think?

I read in mushrooms demystified about soaking in wine for 3 months. Has anyone tried this?

It is growing on Oak. I v always herd G.tsuage grows on conifers Hemlocke hence the name.

I found this same species of Ganoderma in San Diego as well, though I do not think that I have come across it in the Bay Area… Not sure which it is.
