Also known as Gold Cap, Golden Halo, Bluestain Smoothcap, Cube
Golden cap mushrooms thrive in warm, humid pastures where herbivore dung provides an ideal nutrient substrate. Their fruiting bodies feature a smooth cap that shifts from conic to convex with age, supported by a pale stem bearing a membranous ring. When the mushroom tissue is bruised or damaged, enzymatic oxidation creates a distinctive blue-green discoloration across the injured area.

Why interaction risk is high
Contains potent psychoactive alkaloids. Many wild mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Why it is dangerous
Contains psilocybin and psilocin, which alter central nervous system function to induce hallucinations, panic, elevated heart rate, and severe disorientation.
How to recognize a risky encounter
Recognized by a golden-brown convex cap, a dark spore print, a prominent stem ring, and clear blue bruising.
What to do
Do not harvest or consume wild specimens, as lethal look-alikes frequently share the same habitat.
Responsible observation
Field Identification: Look for a yellowish-brown cap that stains blue where bruised or handled.
Habitat Awareness: Search pasture environments after warm rainfall where herbivore dung is present.
Safe Observation: Avoid picking wild fungi to prevent accidental poisoning from dangerous look-alikes.
