Fungus Humongous



""Don't look now, but there's a humongous fungus among us!" "

- Red Green

Sometimes in fantasy works there are mushrooms that are larger than average. While some actual mushrooms have been known to grow as large as soccer balls, in fiction mushrooms can grow to be as large as people, or even trees, leading to whole forests of nothing but mushrooms. Sometimes they are merely supposed to be an unusual flora used to convey the alien nature of the place, when unreal or differently sized trees, grass, and the like just wouldn't seem alien enough. Other times they are supposed to show corruption, an evil blight that is spreading across the land.

Does not apply to tiny people living in regular mushrooms, since in those instances it is the people that are unusual, not the mushrooms. Also does not apply to mushroom clouds, which are just mushroom shaped. Nor does it apply to sentient fungi, since they are not necessarily part of the scenery, unless they are so humongous that they dominate the scene. See Mushroom Man for that sort of thing. Of course, if they live in giant mushrooms, that is another matter. However, it may cross over with Springy Spores if it's in a video game level.

Named after the fun wordplay "A fungus among us" that pops up in many different forms of media, including an album by Incubus.

This is usually considered a Plant Trope, even though fungi are not, you know, plants.

Anime and Manga

 * Nausicaa of the Valley of the Wind, Nausicaa's home planet is overrun by massive fungus. In the manga, it's shown that one type of fungus can grow to a height of 30 meters in seconds.
 * In volume four of the Moyashimon manga, the legion of A. oryzae mold spores (which Sawaki can see and speak to) that have taken up residence in his dorm room bother him while he's reading a manga... and then combine into a giant oryzae and sit on him when he won't pay attention to them. Sawaki also sees large concentrations of other microorganisms as room-sized miasma blobs with big grinning faces.
 * In Naruto: Kakashi Gaiden includes a forest with very large trees with mushrooms so large you can stand on them.
 * Urusei Yatsura. At the end of his competition with Lum, Ataru pursues her in an area where giant (building-high) mushrooms have burst out of the ground.

Comic Books

 * The Tintin story "The Shooting Star" involved a rocky meteorite the size of a small island that mysteriously sprouted mushrooms and other creatures that quickly grew to giant size and exploded.
 * One page of Little Nemo in Slumberland found Nemo walking through a forest of giant mushrooms so utterly fragile that they all collapsed when Nemo stumbles against one.
 * La Forge de Vulcan has a few pages set in a forest of tree-sized mushrooms, stated to be brought by the Vineans from their world. They have not returned since, but fit the pattern for other Vinean lifeforms of being our familiar wildlife (very well-drawn), modified in a single respect (size, colour, number of limbs) or combined together.

Film

 * A giant mushroom appears in Disney's Alice in Wonderland. One half of the mushroom made Alice huge, while the other made her tiny.
 * The live action adaptation of Super Mario Bros. has a giant fungal growth covering the whole city
 * During the "Order 66" bit in Star Wars: Revenge of the Sith, one of the Jedi to die is on Felucia at the time. Something of a subversion in that most of the fungi on Felucia looks nothing like Earth fungi.
 * Indeed. Most people immediately after the film referred to the planet as "Doctor Seuss Mushroom World". That's how strange Felucia looks.
 * Dreamcatcher the film of the book by Stephen King has a race of parasitic aliens whose biology and spaceships are based on fungus—like those fungal parasites that eat ants from the inside out. This allows them to blow up their ship like a puffball if attacked.

Literature

 * In Journey to the Center of the Earth by Jules Verne, the main characters find giant petrified mushrooms in a huge underground cave.
 * Alan Dean Foster's Star Wars Expanded Universe novel Splinter of the Minds Eye. Luke and Princess Leia crossed a lake using the caps of giant mushrooms as kayaks.
 * Massive fungi (I don't recall them being specifically mushroom-like, though) show up in H. G. Wells's The First Men In The Moon. Eating them induces euphoria and intoxication.
 * Eleanor Cameron's Mushroom Planet series.
 * Zack Parsons's serial story Instructions For A is worth reading without spoilers. However I'll say that.
 * In The Forgotten Planet, Murray Leinster carefully justifies this by giving the planet patterns of weather that make photosynthetic life forms non-viable, allowing saprophytes to fill the niches occupied by trees, grasses, etc.
 * These things spouted from the ground around the city of Ambergris sometimes in mere hours in Jeff VanderMeer's City of Saints and Madmen: The Hoegbotton Guide to the Early History of Ambergris, as foreshadowing to the mysterious incident known as the Silence where two thirds of the city's population mysteriously vanished overnight without a trace, along with all the mushrooms.
 * In the sequel novel Finch the city is overtaken by the Graycaps, and their giant mushrooms grow to the size of buildings, and periodically spew out spores that are delicious and nutritious, but also contain extremely addictive drugs, and are used for population control.
 * The Tunnels series has a massive fungus that grows inside the Pore. Its shelf-like protrusions can provide a soft landing for some of those unfortunate enough to fall in.
 * Piers Anthony's Omnivore is set on a planet where animals never arose, but some fungi did evolve mobility. In addition to plenty of oversized stationary fungal species, there's an omnivorous mobile type the size of a minibus. (Also sentient mobile carnivorous ones, but that's a different trope.)
 * In the second of Elizabeth Bear's 'Jacob's Ladder' books (Chill) there are several levels inside the Generation Ship where massive insects and fungus have developed in humid darkness resulting from wonky life support- two characters make camp on a shelf the size of a mattress.

Live-Action TV

 * An episode of The X-Files featured a Monster of the Week which was a giant underground fungal complex (see Real Life below); the nonsentient growth sucked down its human victims and dosed them with powerful hallucinogens to keep them docile while it slowly digested them.

It then proceeds to make a 1/1 creature token at the beginning of each of your upkeep phases for each counter on it. With the right cards, you can also give it more +1/+1 counters each turn, turn it into a Fungusaur, make the creature tokens it generates have power and toughness equal to how many of them are in play...

Strangely, in WoW's Outland - the place that remained of Draenor after its destruction - the only place where giant mushrooms grow is Zangarmarsh.

The same cannot be said, however, for the mind worms that lurk in the fungus...
 * Harmless fungus? Except during the twenty year cycle of the secondary star periastron, in which case fungal growth is so violent it will blow up mines, farms, solar panels, and tube trains. With a big boom and a fireball. So... Mostly Harmless.

In particular is the Sea of Spores, which in addition to being inhabited by giant fungi of many varieties (including ones that attack you), is filled in every direction by a literal fog (or snow) of spores from them. It is so bad that there is a giant domed forcefield to keep the damned thing from spreading. One wonders how the little dragons breath or the stone golems don't get broken apart by fungus growing all over them. However, aside from this being a fairly good place for low 40's to grind and being part of a class change quest, this area is almost entirely ignored. That is, if you don't count Orfen, the fifty foot six-armed spider queen that hides in there.
