What If Our Heads Were Mushrooms?

Fig 1. Scary Glowing UFO Mushroom

Think about it.

If our heads were replaced with with glowing, multicoloured fungi.  As we walked, we would spread spores all around, breeding new mushroom-heads that would grow up around us.  Then again, it may cause overpopulation problems, so that would have to be dealt with.  Perhaps unnecessary mushroom-heads could be eaten.  It would be nutritious!  

I still think it would be cool though.  Different mushrooms could could indicate social status, vibrant Lactarias Indigo would sprout from the necks of the rich and privileged, and the poor and downtrodden would posses mere Fly Agaric for noggins. 

We'd have to maintain them of course, and water them and things like that.  Knowing humans, rituals would probably form this process.  Watering rituals.  Yes.

This post made more sense in my head.
