Deep in the mountains of Japan, a flying saucer smashes into the earth. Fearful of the strange and hyper-intelligent beings they find inside, the government hides from the public all news of the alien craft. But it's not the aliens themselves that they should be afraid of-the real danger is the parasitic spores they brought with them! Will earth survive the UFO MUSHROOM INVASION?! Originally published in 1976, Shirakawa Marina's UFO MUSHROOM INVASION is unanimously considered a masterpiece of Japanese sci-fi horror. Pulling on his deep knowledge of Japanese ghost stories and folklore, Shirakawa serves up one of Japanese comics' cult classics and an unforgettably creepy entry in the canon of spore-horror. UFO MUSHROOM INVASION is the second volume of SMUDGE, a line of classic pulp, horror, and dark fantasy manga, curated and translated into English by award-winning historian Ryan Holmberg.
