![]() Microorganisms and harmful bacteria can infect them, even in a clean environment. It’s impossible to control the potential contaminants present during making, storing, and using spore prints. They’re unique, fascinating, and easy to create but aren’t the best choice for research and microscopy. Mycologists make and use these prints to help identify fungi, log their foraging finds, and build up their sample libraries. It’s a useful taxonomy and research tool, indicating spore color, cap shape, and size of a particular mushroom species. Spore Prints: Identification and Investigation ToolsĪ spore print is a patterned imprint made by collecting a mushroom’s reproductive cells onto a surface like paper or foil. But this excludes any psilocybin-containing species which are illegal to grow in the US and various other countries. While multispore liquid cultures are common, isolated, single-strain LCs are usually preferred for growing gourmet mushrooms.Īs for research, LCs are a fun way to see mycelium in action. After brewing, the inoculant fluid is pulled into a new syringe. LCs are made by combining germinated spores with a nutrient-rich yet sterile solution. Their shelf-life is shorter, though, lasting about six months when refrigerated. They typically have quicker colonization times than starting from spores. That’s why cultivators prefer liquid cultures for edible gourmet mushrooms. ![]() If spores are like plant seeds, then mycelium is akin to a seedling. While spore syringes consist of ungerminated reproductive cells, LC injectors contain a mushroom’s next life cycle stage: mycelium. It’s filled with live mushroom mycelium suspended in a sterile, nutritive solution. Liquid Cultures: Live Mycelium for Gourmet MushroomsĪ liquid culture (LC) syringe is also an injector tube with a Luer-lock needle.
