Does Trametes gibbosa have any redeeming qualities other than eating wood?

I've got a ton of what I think must be Trametes gibbosa or elegans (a.k.a. Lumpy Bracket, Lenzites elegans, Daedalea elegans) growing on all my felled sweetgum logs. It starts out looking like a lump of rubbery grey chewing gum, then grows into a shelf bracket with lumps close to where it affixes itself to the tree. It's white and sometimes greyish, slightly yellowing when the pores are rubbed when fresh, has a white spore print, very large spores, and that slot-like look to the pores on the underside. I read that it's European in origin and has been identified as a possible invasive in North America.

If somebody wants to see it, I'll post some photos, but mainly I'm wondering: for those who have identified this polypore, have you found any decent uses for it as tea or extracts? I've read several scientific studies online that show T. gibbosa is far less potent than T. versicolor or T. hirsuta, but is it completely worthless medicinally? One foraging site said it's inedible (too woody, bitter). But it seems to be calling to me to ingest it somehow. Of course, I am suspicious of such siren songs....

The book entitled The Fungal Pharmacy, by Robert Rogers,  states "The related Trametes gibbosa has an inhibition rate of 49% against sarcoma 180 with hot-water and ethanol extracts. It is a very strong inhibitor of both 1 kappa B-alpha degradation and phosphorylation." This is the only reference to the medicinal qualities of this species I can find. Trametes versicolor has had much more research done on it and its healing qualities, so it probably would be a much safer species to use.

I saw that info in one of the NIH articles I read. Of T. versicolor, T. hirsuta, and T. gibbosa, the latter was the weakest (49%). But I just found this article, which is interesting, if over my head:

Googling the scientific name plus "scholarly articles" definitely gives more hits than searching for "lumpy bracket," which is what I started with. There was a whole list of various studies of T. gibbosa!
