Gymopilus Mushroom Spore Prints

Gymopilus Spore Print

The Gymnopilus thiersii Mushroom Spore Print from Magic Spore Labs delivers basidiospores from a wood-decomposing fungal species with an unusually precise taxonomic pedigree. Formally type-located at Wunderlich Park in San Mateo County, California, Gymnopilus thiersii carries a verified geographic provenance that distinguishes it from many Gymnopilus species with broader or less documented collection histories. For researchers building multi-genus reference collections, that precision matters — and the species' distinctive morphological and chemical profile makes it worth studying closely once it's under the microscope.

G. thiersii is characterized by rusty orange-brown basidiospore deposits, a conical cap that develops a distinctive shiny appearance when dried, and brownish-orange gills with an open, non-compact structure. What elevates it as a research specimen beyond its visual traits is its dextrinoid spore chemistry — a reactive property in which spores stain blue-green when damaged, a chemically verifiable identification characteristic not observed in Psilocybe or Panaeolus species. For microscopists studying spore reactivity, wood-decomposer taxonomy, or the structural diversity of basidiospores across genera, Gymnopilus thiersii provides a genuinely distinctive data point that no cubensis strain can replicate.

Magic Spore Labs produces every Gymnopilus thiersii spore print under GMP-aligned sterile conditions, depositing a dense, uncontaminated basidiospore sample onto individually sealed sterile aluminum foil substrate. Prints store at ambient temperature for up to 24 months with no refrigeration required. We ship to researchers across the United States, excluding California, Idaho, and Georgia. All products are sold strictly for microscopy and taxonomy research purposes only.
