A spore print is a method used to identify mushrooms by capturing the spores they release. To create a spore print, a mushroom cap is placed gill-side down on a piece of paper for several hours. The spores fall onto the paper, leaving a pattern that can help determine the species of the mushroom. The color and pattern of the spore print can vary widely among different types of mushrooms, making it a useful tool for mycologists and mushroom enthusiasts. This technique is particularly helpful in distinguishing between edible and toxic species, such as Agaricus bisporus and Amanita phalloides.
