You're probably thinking of a "fungus that shoots spores", but there's no single fungus species that does this in a literal sense. However, many fungi do release spores, and some have mechanisms that facilitate their dispersal:

* Ballistic Spore Discharge: This is the closest to "shooting" that fungi get. Some fungi, like Pilobolus, launch their spores with incredible force using a built-up pressure system. This propels the spores through the air, allowing them to travel much further than simple wind dispersal.

* Spore-releasing structures: Many fungi have specialized structures, like basidia in mushrooms or asci in cup fungi, that release spores. While not "shooting" in a literal sense, these structures release spores in a variety of ways, including bursting open, dropping, or even being carried by insects.

* Wind dispersal: Most fungi rely on wind to carry their spores, which are often light and sticky to help them adhere to surfaces.

So, while no fungus "shoots" spores like a gun, there are many species with fascinating mechanisms for releasing and dispersing them far and wide.

If you have a specific fungus in mind, I might be able to give you more details about its spore dispersal method.
