there's always that ozone spot with more than 20 just huddled together.
I might've gone wandering a bit too soon, most purps i found weren't fully matured and there's lots of fresh debris from the storm.
I've found they seem to be quite content around salt flats, on dead paperbarks. as to the soil content not sure about alkaloid presence i can't say I've tested it. I really wanna extract the colour from this particular fungus and dye my clothes with it I LOVE the maroonish-purple, i think it'd make a great colour for a pair of pants
