The structure of Psilocybe samuiensis 

All Psilocybin mushrooms are unique in their own way. Let’s talk mushroom details!


The cap, usually 7–15 mm wide, has a slightly rounded to cone shape, showing off a small bump in the center. It has a sticky and filmy skin you can peel. When it’s wet, it’s reddish-brown, but as it dries up, it lightens to a nice brown shade.


They are clay-colored; when dry, the gills turn a violaceous brown or chocolate-violet color with whitish margins.


About 4.0–6.5 cm tall and 1.5 cm thick, the stipe is like the cap’s partner in crime. It’s hollow, whitish, and dressed in these white threads. It’s the same color as the cap.


When injured, it will stain blue.


Around 10.4-12.8 by 6.4-8 μm, with a thick wall and a wide little opening.

Spore print

The spore print is dark brown to purple.

Habitat and Distribution

Psilocybe samuiensis thrives under specific conditions. It seeks out areas abundant in decaying organic matter, often making its presence known in the company of fallen leaves and decomposing wood. The mushroom’s growth is a testament to nature’s ability to transform the ordinary into the extraordinary.

Discovering the Enchanting Enigma of Spores 

Sometimes, similar strains can seem like twins. Researchers can tell them apart by checking out the spore color and print. Spores are the tiny structures mushrooms use to reproduce, and their colors vary across species and even within the same group.

You can easily distinguish lookalike strains and sort mushrooms into proper categories; all you need are purebred spores. That’s where Fungushead comes in – we offer mushroom spore syringes, swabs, and mixpacks.
