Edit request from Sublimehypocrisy, 17 December 2010 

The fruit page mentions plants only. However, there is another example of a fruit. 

When a fungus grows to the point that it can produce spores, the portion of the fungus that contains the spores, or fungus seeds, is considered the fruiting body of the fungus.

Currently, the fruit page only gives information about plants being fruits but even the fungus Wikipedia article states that the mushroom is the fruiting body of a fungus. I hope someone can confirm the validity of my claim.
