Gymnopilus Thiersii Wild Spore Print

Gymnopilus thiersii is a less commonly studied species outside the Psilocybe genus, making this spore print a useful addition for researchers building a broader comparative reference set across genera.

The Gymnopilus Thiersii wild mushroom is often characterized by its rusty spore deposits, conical cap, and habitat. It’s commonly found growing on wood, with brownish-orange gills that are not tightly compact. This species tends to develop a shiny appearance on its cap when dried. Its spores are dextrinoid and will stain blue-green when damaged. The type location for G. thiersii is Wunderlich Park in San Mateo County, California.

Visual & Microscopic Characteristics: Spores typically present as rough or finely roughened-walled and rusty-orange to brown under magnification — a useful contrast point against the smooth-walled spores typical of Psilocybe species.

Research Notes: Gymnopilus species are frequently referenced in spore ornamentation studies given their textured spore walls, a key taxonomic differentiator from smoother-spored genera.
