Our Story
Born at Altitude. Built for Curiosity.
Mile High Mycelium started in a Denver basement with a microscope, a notebook, and an obsession with fungal genetics. We've grown into one of the most trusted sources for premium spore specimens in the country — but the obsession hasn't changed.
Why We Do This
Mycology is one of the last great frontiers of citizen science. The fungal kingdom is vast, poorly understood, and endlessly fascinating — and spore microscopy is one of the most accessible ways to explore it.
We source and preserve genetics from around the world, document spore morphology with obsessive detail, and make that research accessible to hobbyists, educators, and professional microscopists alike.
Every specimen we offer has been examined under our own scopes before it ships. If the spore print isn't clean, the syringe isn't dense, or the swab isn't viable — it doesn't leave our lab.
Microscopy Research Guide
New to spore microscopy? Here's everything you need to get started examining fungal spores at home or in the lab.
Choose Your Microscope
A compound microscope with 400x–1000x magnification is ideal for spore examination. Look for models with a mechanical stage, coaxial focus, and at least a 40x and 100x objective. Oil immersion (100x) reveals the finest spore surface details.
Prepare Your Slide
For spore syringes: deposit a small drop onto a clean glass slide and apply a coverslip. For prints: use a sterile scalpel to scrape a tiny amount of spore material into a drop of distilled water. Avoid air bubbles under the coverslip.
Focus and Observe
Start at 40x to locate spore clusters, then increase to 400x for individual spore morphology. Note shape (ellipsoid, subglobose, fusiform), surface texture (smooth, warted, striate), and color under transmitted light.
Document Your Findings
Keep a research journal with strain name, collection date, magnification, and observations. Photographs through the eyepiece (afocal method) or a dedicated camera adapter create a permanent visual record.
Store Specimens Properly
Spore syringes store best at 35–46°F (2–8°C) in the refrigerator. Spore prints should be sealed in foil or plastic wrap and kept cool and dark. Properly stored specimens remain viable for 12–24 months.
