I did find a lot of similar information; however, what I could not find was a picture that looked like the specific species of mushroom (if the picture above is unclear, it is very similar in size and colonization pattern as the last group of mushrooms in your link, but gray, taller, and with thinner stems). It's good news and new information that apparently the mushrooms are not harmful, but do you know about the affects of rotting in the tree that the mushrooms indicate? Or how significant of a problem root rot would be on a Fukien?
