I don't remember what the original question was but I have simmilar Mushrooms
groing in my Nepenthes meedium.  It seemed to have gotten there with the
Osmunda fiber that I use.  I don't mind them - yet.  It seems that they only
grow in the winter when the temps are cooler, and only after I sut watered
the plants.  They are pure white and stand about 4cm tall wtith the caps
about 1 cm in diameter.  It seems that the plants don't mind them and the
medium so far is holding up too.  
My 2c worth...
