Bonsai Ginseng...... please advice
 

Hi everybody,

I bought 2 Bonsai Ginseng 1 month ago, they are both in pots and
indoors beside the window, they are both about 10 years old . I just
noticed today that one of them has some "mushrooms like" or maybe it is
mushrooms small heads are coming out from the mud in the pot near the
main root of the bonsai! I do not know what is it and my wife says that
this must be mushroom and it must be taken off! We both are not really
sure what this is , the plant looks healthy though!

Thanks a lot for your appreciated before hand advice.
