Melmac Mushroom[i][ii] is a strain of Psilocybe cubensis, one of the world’s most popular psychoactive mushrooms. The name is probably a reference to the old TV show, Alf, whose title character was a rather aardvark-like space-alien, the idea being that this mushroom is “out of this world.” It is a little odd-looking, with a thick, contorted stem and a wavy, often split cap. Many P. cubensis strains rather stretch the definition of “strain,” as they are not really all that different from other mushrooms of the same species, but Melmac is pretty distinct. Melmac is a variant of Penis Envy, an admittedly phallic-looking shroom that’s been popular for decades (it’s not especially envious). Melmac doesn’t look much like Penis Envy, but the two have a lot in common otherwise. The strain was developed through deliberate breeding (rather than being found growing wild, as some strains are) by a grower working to stabilize an interesting variation within the original genetics of the early Penis Envy stock.
