A flying saucer crashes deep in the mountains of Japan. Wary of the hyper-intelligent beings they find inside, the government hides from the public all news of the alien craft. But it's not the strange visitors themselves that they should be afraid of-the real danger is the parasitic spores smuggled aboard! Will Earth survive the UFO Mushroom Invasion?! Originally published in 1976, Shirakawa Marina's UFO Mushroom Invasion is a masterpiece of sci-fi horror. Pulling on his deep knowledge of Japanese folklore and the supernatural, Shirakawa serves up one of manga history's cult-classics and an unforgettably creepy entry in the canon of spore-horror.
