Panaeolus cambodginiensis (Copelandia cambodginiensis) is a mushroom that grows on the dung of the water buffalo. Luckily you don't have to that at home. Its name refers to Cambodia where it originates although nowadays it can be found throughout Asia and Hawaii.
Please note: The solution in this spore syringe is black. A little carbon has been added to protect the spores from bacteria.
