way to see the resin is not to cut it open, but rather prick the white growing edge with something like a needle. The link below is an artificially cultivated resinaceum that I pricked to demonstrate.

I don’t see any yellow resin :-(

Ganoderma resinaceum is an interesting idea,

The mushroom is growing back this year. I will check to see if it has that yellow resin oozing out of cuts that G. resinaceum is supposed to have.

Here is a good article on Ganoderma

The lucidum I know

is uniformly red laquered has no diversely colored growth zones, is smaller and has a marked stipe-like structure.
What are the trees that stand in some distance? It would be helpful to get to know the substratum (as said, roots or buried wood).

Yes, Ganoderma is still a mess. The biggest mess it is in South Asia/Northern Australia. I have so many collections from the area running under spec. …

Other than G.lucidum?

I don’t know any other Ganoderma species around here, except G.applanatum, which is different, and G.tsugae, but there are no conifers nearby. If anyone knows other species that might be present in the area, I’d like to hear about it (most books recycle 3 aforementioned species, but I’m sure there are more).

Must be in touch with some wooden substance.

I assume it grows on roots of trees or on some buried wood. Plus I wouldn’t call it lucidum but a Ganoderma it is.

Growing on the ground, fair distance from any trees
