Panaeolus bisporus Spore Print

Spores are supplied as spore prints on heavy foil. Each print is individually packaged and prepared for clean, stable storage. Spore print size and density may vary by species and variety.

Panaeolus bisporus is a rare and taxonomically important Panaeolus species confirmed to originate from Colville, Washington where in August 2010 it was collected by Frizzie, also known as Subbalteatus. This North American collection is notable because P. bisporus was historically better known from the older type-locality region of Morocco and nearby Spain, while this material represents a confirmed continental USA origin.

Panaeolus bisporus is associated with temperate conditions and has been reported from regions including North Africa, Spain, Switzerland, Hawaii and the continental United States.

Habitat: manure and enriched soils
Climate: temperate to Mediterranean
Origin: Colville, Washington, USA

Microscopic distinction: Panaeolus bisporus is separated from Panaeolus cyanescens primarily by its exclusively 2-spored basidia. This makes it a particularly useful Panaeolus reference print for species-level comparison within the genus.

Phenotype: young fruit bodies generally show very dark lead-gray to nearly black caps, fading toward light gray at maturity.

Spores: black in deposit. Species-level identification relies heavily on microscopic features, especially the 2-spored basidia.

For customers comparing Panaeolus prints, it is a useful counterpoint to tropical TTBVI and Caribbean Jamaica material.
