can any body give me ....10 differences between annual ...and perennial fruiting bodies..??

Ummm, this sounds like a homework question. Not sure I should give you the direct answers here.

I can think of about 5 right off, but beyond that I'd probably go to the text books for definitions of ‘annual’ and 'perennial’. Are you studying mycology in general or pathology?
