Panaeolus cinctulus

Common name: Banded Mottlegill

Field Identification

Cap2–5cm; convex; dark brown at margin, paler (cream to tan) at center when dry — the 'banded' appearance from different moisture zones; hygrophanous; smooth
GillsAdnate; gray-mottled pattern as spores mature unevenly — a characteristic of the Panaeolus genus
Stem5–12cm; pale gray; fibrous; straight; no ring; slightly enlarged at base
Spore PrintJet black; lemon-shaped (limoniform) — distinctive
HabitatCompost heaps, well-fertilized lawns, gardens, dung-enriched soil; suburban and agricultural settings worldwide; often found in flower beds and compost piles
DistributionCosmopolitan — worldwide in temperate and subtropical zones wherever suitable nitrogen-rich substrate exists; one of the most widely distributed psilocybin mushrooms in North America
SeasonApril–November; spring through autumn with moisture

Key Identification Feature

The mottled gray gills (spores maturing unevenly) and jet black spore print are the most diagnostic features. Found in compost and fertilized lawns. Distinguished from Panaeolus papilionaceus by habitat preference and from P. cyanescens by lack of strong bluing and different habitat.

⚠ Dangerous Lookalikes

Panaeolus papilionaceus (non-psilocybin; dung habitat; similar but often has remnant veil fragments), Panaeolus cyanescens (much higher potency; stronger bluing; tropical/subtropical habitat preference), Stropharia semiglobata (on dung; different cap texture and spore print location)

Notes

Panaeolus cinctulus (also known as P. subbalteatus in older literature) is arguably the most commonly encountered psilocybin mushroom in suburban North America, yet it is frequently overlooked because it appears in ordinary garden settings. Unlike most psychedelic mushrooms, it does not grow on dung directly or in remote habitats — it colonizes compost and nitrogen-rich soil wherever humans garden. The 'banded' cap (lighter center, darker margin when moist) and jet black spore print are reliable identification features. Potency is lower than P. cyanescens but the wide distribution means accidental ingestion by gardeners handling compost has been documented.

Legal Status Warning Psilocybin-containing mushrooms are controlled substances in most jurisdictions. This guide is for educational purposes only. Wild foraging for psilocybin mushrooms may be illegal in your location. Never consume wild mushrooms without positive identification from an expert mycologist — misidentification can be fatal.
