Fine. Some fungus is toxic, some is not. I had this white fuzzy fungus appear on my Mopani and within a day or two the tank water clouded a bit and the fish were clearly having trouble respirating (corys sat on the substrate breathing fast). Pulled the wood out, did a major water change, end of problem. Cleaned the wood as you have, put it in a tank with no fish, for 2-3 months seemed fine, so used it in another tank with fish, and noticed after a couple months the fish were dying off, and then saw some white on the back side. Tossed the wood, not worth the risk.
