These three terms get mixed up constantly, and picking the wrong one wastes money. They are not three versions of the same product. Each one contains something different, and each suits a different job.
Spore syringe
A spore syringe is a sterile syringe (usually 10ml) of water with spores suspended in it. The spores are tiny reproductive cells that cannot do anything until they germinate. A syringe is the most convenient way to put a few drops of spores on a microscope slide, which is why microscopists favour it. You can browse our spore syringes, each labelled with its species and strain.
Store a syringe in the fridge at 2 to 8 degrees C and out of light. A syringe that looks cloudy, coloured or has clumps floating in it should be discarded.
Spore print
A spore print is what you get when a mature cap is left gill-side down on paper, foil or glass and drops its spores in a pattern. It shows the spore colour, which is one of the main clues for identifying a mushroom. Prints keep well when dry and can be scraped into water for a slide. They are the traditional tool of field mycologists. Our guide to identifying mushrooms by spore print and spore shape explains how to take one.
Liquid culture
Liquid culture is different in kind: it holds living mycelium (the vegetative body of the fungus) growing in a nutrient solution, not spores. You inject 1 to 3ml into sterilised grain or substrate and the mycelium carries on growing. That makes it a cultivation product. We sell it for gourmet and medicinal species only; see our liquid culture syringes, including Blue Oyster and Lion’s Mane.
Which should I choose?
- Studying spores under a microscope: a spore syringe or a print. A syringe is easier to use and arrives sterile.
- Identifying a mushroom you found: a spore print you take yourself.
- Growing oyster, Lion’s Mane or reishi: liquid culture, or a ready-made kit that you inoculate with it.
One practical point: spores and mycelium behave differently in a lab. Spores give genetic variety, so each one can differ slightly. Mycelium is a clone of its parent. If you care about consistency, mycelium is the more predictable material; if you care about studying a species’ spores, you want the spores themselves.

Our spore syringes are sold for microscopy and research only. Growing mushrooms that contain psilocybin is illegal in the UK. This guide is general information, not legal advice. You must be 18 or over to buy from this shop.
