Mushrooms with Petals?

These mushrooms - which I discovered growing outside my local Best Buy - are more interesting looking than your typical undead grey variety of fungus flower.


Perhaps they're a rare breed that grow only when nourished with the unrequited tears of true geeks pining for tech they can never afford?

I wonder if it would be healthy to have decorative mushrooms growing in pots in a home? Could you encourage deeper colors by introducing dyes to their water?
