There is a sporeless oyster species, but most of them do drop spores that can be collected on a piece of tin foil by letting it sit on the foil for a few hours. Oyster spores are actually super toxic and six months of exposure without a respirator can cause a lifelong allergy to them, mushroom worker's lung.

Very interesting! I would assume the all in one kits that people have are the sporeless kind then
