I’ve been eying some mushrooms that I thought were edible. To help make a correct identification I did a spore print on one of them. This is a way to get more information on a type of mushroom (different mushrooms have different colored spores) as well as a cool art project.
Basically you put a piece of white paper next to a piece of black paper and put the mushroom cap on top. You need both colors of paper if you don’t know what the spore color is because it might be light or dark. Then you cover the whole thing with a bowl and let it sit for 24 hours.
I came back to this beauty:
You could even take this a step further and try to find shapes and images in the print. The spores will rub off the paper but you could try spraying with fixative if you wanted.
A more defined cap will produce a more defined image. Experiment!
