Horses don't react to red specifically, but running close past a group of unknown horses is never a good idea. :)
It's fun when a group of dane owners walk past a group of horse riders - each group eyes off the other waiting for someone to make the first 'saddle' joke.
If QI has taught me anything, it's not the colour that stirs up the beast but the movement of the object that attracts attention.
Speaking of red mushrooms, I saw a very bright red one with white spots on one of the maps over in NSW (in the terrain, not specifically on the map). I would have to wonder what would happen if you ate it.
Hallucinations! Apparently "parboiling breaks down its toxins"

OK. Ingrained mythology from farming grandparents that used to point out we shouldn't run in our red tracksuit pants in the bull paddock. As per the horses, probably still a good idea to have stopped us running around in the bull paddock. :)
Red mushrooms sound poisonous to me. This one looked like a regular white button mushroom with stem and cap except it was incredibly big and growing out of a tree trunk.
Yeah that looks like it and it was in a pine plantation. I've never found 'shrooms before. Probably a good thing I didn't eat it before the race!
I've seen them lots in pine plantations when orienteering/rogaining and they are beautiful. Aren't those the toadstools under which elves make houses?
Mind you, the death cap mushroom is also an Amanita:

I'm pretty sure Araminta was a character in a book I just read. Any relation?
