Rusty Albino A+[i], or AA+, as it is sometimes called, is a cultivated strain of the well-known psychoactive mushroom species, Psilocybe cubensis. It’s typically cream-colored to white, sometimes with a bluish tint—when damaged, it bruises blue very obviously. The spores are purple-black, and once they mature, they will cover the stem-ring and make it appear black. Because these mushrooms have reduced pigmentation, not none at all, they are technically “leucistic,” not albinos. That’s good news for growers, since real albino mushrooms have colorless spores that are almost invisible and thus very hard to work with.
There is persistent speculation that Rusty albino A+ is actually part-Panaeolus, since its high is reportedly reminiscent of the effects of some of the more potent Panaeolus species. Actually, such hybridization between different genera is likely impossible, but there may be some coincidental biochemical similarity.
