Charlie,
Isn't there a fungus named Shelf Fungus or Shelf Mushroom?
By the By, thanks for teaching me that English phrase. I have been trying to use it where applicable as have some of the others.
I will try to teach you one in return:
In college, I had a friend from England. One day I was telling him about my romantic endevors and he replied that I had been SHAT UPON. I think that must be English for mistreated.
