Terribly sorry for the late reply as I haven't been on here. I cannot see the link. But I will say, yes Ganoderma can and do cohabitate with other polypores including other Ganoderma. I have seen 3 different Ganoderma species growing from one tree.

Alas, you are missing the king of polypores in your party.

I do not, but if I had this question (not entirely unrealistic expectation) you would be the person I would ask,so I hope you find an answer, lol. Also if you do please share sources. ☺️
