Yesterday I found a small white mold signs underneath description paper (Nei Piao) on my pu-erh cake. Mold is believed to be not healthy on tea, so had to remove it gently with the knife.
I guess in our humid and hot weather (I live near sea shore) the description paper made the moisture accumulate beneath. This Nei Piao is not made of porous hand made paper, but regular paper. Had to remove it to allow better air circulation on my cake. Hope the cake is gonna be ok now.
Sorry, I forgot to make a picture of mold, but here are some links to see what is it looks like:
