Great Northern Whites are an isolation of Melmac, a P. Cubensis strain that is closely related to Penis Envy. The distinguishing characteristics of Melmac mushrooms are their wavy cap and contorted stems. Like many other psychoactive mushrooms, they take on a deep blue color when bruised. Melmac is known to be relatively high potency, meaning you’ll need smaller doses of the mushroom than you would for an average P. cubensis to get the same effect. These Great Northern Whites are dehydrated and have a more pleasant smell than other varieties, almost chocolatey.
