I think for most of us the sight of anything growing on our tea is cause for concern. Dry it out! Wait it to go away! Or, if it's really bad, throw it out altogether! And without knowing what you're doing it would make sense to avoid any signs of fungus. There are so many kinds of fungus in the world and some are harmless even delicious some will kill you, and some just take like crud.
So, take a look at:
AnHua Gold flower
This tea is not pu'erh (why not?) but it claims to be "better than pu'erh" (big claim!)

Also fungus is a selling point! Really?
How old is this concept? Is it popular or more of a "fringe" tea?
Is it better than all pu'erh? (I HIGHLY DOUBT IT!)
But is it good?
Is this the same fungus found on puerh some of the time?
Would pu'erh even age without some mostly invisible fungus at work?
Too many questions?
