When you buy Melmac spores, be aware that they’re considered “active spores” which are for microscopy purposes only. DO NOT CONTACT US ABOUT ANYTHING REGARDING CULTIVATING OR GERMINATING MELMAC SWABS. 

Shipping is unavailable to California, Idaho, & Georgia. These 3 states strictly prohibit the possession of spores from psilocybin and also psilocin producing mushroom species. Orders to these states are refused and subsequently voided. Any payments made for orders to CA, ID, or GA will incur a $5 cancellation fee. 

The provided images are for informational and educational purposes only and are used as a reference point only.

We do not condone or participate in the cultivation of psilocybin or psilocin producing mushroom species. 

When you buy Melmac swabs, spore visibility is dependent on the characteristics of the spores themselves. As a result, not all spore swabs will look the same visibly. Despite any visible differences, they’re still viable for microscopy research.

Melmac Mushroom Strain Information

Melmac is the original Penis Envy genetics that was sold in mushroom grow kits from a store in the 80’s and 90’s. The store went by the name “Melmac Homestead” and it was the Hot Topic of its time. The genetic mutations of this variety causes a deformity that doesn’t allow the caps to fully open. Consequently, the unopened caps make them look like a phallus, which is how Penis Envy came to have its name. In other words, the name evolved from Melmac to Penis Envy.

Microscopic Features

When you buy clean Melmac spore swabs you will see the spores as dark purple to brownish. The spores are subellipsoid (ellipse) shaped and they are present on a 4-spored basidia. The caps can be a diameter of 50+ mm but will rarely open fully up.  These have diminished spore production from their mutation and only 25 percent will produce spores. So that makes these spores very difficult to acquire, just like the other Penis Envy’s.

Additional information


Subtropical. These mushrooms are known to thrive in subtropical climates places where summers get hot and humid, and the winters are mild. Usually these climates are found between the latitudes of 25 degrees and 35 degrees and the southeast side of all continents.

Research Difficulty



Extremely Light Depositor Mushrooms that typically have problems with producing spores, either because of genetic lineage or species variability. Typically these mushrooms produces spores on 50 percent or less of fully mature fruits and rarely drop them from the gills.
