->''"Don't look now, but there's a humongous fungus among us!" ''
-->-- '''[[Series/TheRedGreenShow Red Green]]'''

Mushrooms that are larger than average appear often in fantasy. 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 [[FantasticFlora 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 [[MushroomHouse 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 [[UsefulNotes/NuclearWeapons 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 MushroomMan for that sort of thing. Of course, if they live in giant mushrooms, that is another matter. However, it ''may'' cross over with SpringySpores 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 Music/{{Incubus}}.

They’ll often be found in alien worlds and settings as a shorthand for the unusual nature of the place, but they also often show up in swamplands, and they’re a staple BeneathTheEarth.

This is usually considered a {{Plant Trope|s}}, even though fungi are not, you know, ''plants''. Can lead to FridgeLogic issues if an entire planetary ecosystem is based on this trope, as even giant fungi can't produce oxygen like plants can.

See ToweringFlower for its floral equivalent.


[[folder:Anime and Manga]]
* ''Manga/NausicaaOfTheValleyOfTheWind'', 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 ''Manga/{{Moyashimon}}'' manga, the legion of ''[[http://en.wikipedia.org/wiki/Aspergillus_oryzae 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 ''Manga/{{Naruto}}: Kakashi Gaiden'' includes a forest with very large trees with mushrooms so large you can stand on them.

[[folder:Card Games]]
* ''TabletopGame/MagiNation'': The entirety of the Underneath is covered in mushrooms, and most of the dream creatures in the area resemble them tremendously. Giant Korrits, Brubs, Vulbors, you name it, it's a mushroom. [[MushroomHouse They make houses out of the things, too]]. Ormagon, possibly the most powerful dream creature in the game, is a colossal, ambulatory mushroom that completely decimated all of civilization in the Underneath in no time at all. For scale, [[http://bluefurok.com/BSImages/Ormagon.jpg the little thing at its feet is a CITY]].
* ''TabletopGame/{{Munchkin}}'' has the Fungus, which is already rather large, but players are encouraged to play the "Humongous" card on it (by giving it a +15 on top of the card's normal +10) to get the Humongous Fungus (which one must never [[{{Pun}} truffle]] with).
* ''TabletopGame/MagicTheGathering'' combines this with MushroomMan in the [[http://magiccards.info/mma/en/163.html Sporoloths]], towering fungus creatures that came from Dominaria's far future during the Time Spiral crisis.

[[folder:Comic Books]]
* The ''ComicBook/{{Tintin}}'' story "The Shooting Star" involved a [[GreenRocks rocky meteorite]] the [[SciFiWritersHaveNoSenseOfScale size of a small island]] that mysteriously sprouted mushrooms and other creatures [[AttackOfThe50FootWhatever that quickly grew to giant size]] and [[StuffBlowingUp exploded]].
* One page of ''ComicStrip/LittleNemo'' found Nemo walking through a forest of giant mushrooms so utterly fragile that they all collapsed when Nemo stumbled against one.
* ''[[ComicBook/YokoTsuno La Forge de Vulcan]]'' has a few pages set in a forest of tree-sized mushrooms, stated to be brought by the [[RubberForeheadAliens 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 [[MixAndMatchCritters combined together]].
* ''ComicBook/{{Zero}}'': In the future depicted in the comic, gigantic mushrooms are shown growing out of the ocean.

[[folder:Films -- Animated]]

%%* Creator/EleanorCameron's ''[[http://en.wikipedia.org/wiki/Eleanor_Cameron#Mushroom_Planet_series Mushroom Planet]]'' series.%%ZCE
* Zack Parsons's serial story [[http://www.somethingawful.com/d/daily-dirt/instruction-for-america.php?page=1 Instructions For A]] is worth reading without spoilers. However I'll say that [[spoiler:it's a frightening take on what our lives would be like if there were a [[https://www.youtube.com/watch?v=CCOQ0VU24xw Cordyceps]] fungi species that could infest every living thing on the planet]].
* In ''The Forgotten Planet'', Creator/MurrayLeinster carefully {{justifie|dTrope}}s 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 sprouted from the ground around the city of Literature/{{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 ''Literature/{{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.
* Creator/PiersAnthony'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 Literature/JacobsLadderTrilogy (''Chill'') there are several levels inside the GenerationShip 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.

* ''Literature/HowTheMarquisGotHisCoatBack'' introduces The Mushroom, which has a tribe of people tied to it by SymbioticPossession.
* BodyHorror extravaganza ''Literature/TheFungus'' features an experimental enzyme that causes fungi to rapidly grow out of control and take over the city of London.

[[folder:Live-Action TV]]
* An episode of ''Series/TheXFiles'' called "Field Trip" featured a MonsterOfTheWeek 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.
* Some large mobile mushrooms appear in one scene of the Music/JohnDenver episode of ''Series/TheMuppetShow''. Denver starts to sing "Nobody Knows the Truffles I've Seen", and the mushrooms [[LamePunReaction attack him in disgust]].

** Zuggtmoy is a [[DemonLordsAndArchdevils Demon Lord]] with dominance over fungus, and that's kind of a problem for her; very few mortals are interested in worshipping fungus. This led her to be used as an UnwittingPawn, by the dark force behind the Temple of Elemental Evil, who tricked her into attracting worshippers, thinking their devotion was granting power to her. In truth, the Temple's true patron was [[spoiler: [[GodOfEvil Tharizdun]],]] and Zuggtmoy ended up a prisoner in the dungeons of "her" own temple for years because of her mistake, and even after escaping, she had lost much of the power she had in the first place.

One progressive Telvanni wizard even gets the idea to blend Imperial and Telvanni styles together, creating the oddest mushroom infested keep ever. Many homes all over the island have potted mushrooms and other fungus as decorations.
** ''The Shivering Isles'' expansion to ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'' likewise features giant mushrooms.
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'':
*** The land of Skyrim itself is mostly mushroom-free, with one very notable exception--the massive cavern called Blackreach, which contains huge glowing mushrooms along with veins of [[PowerCrystal Soul Gems]] and ancient [[OurDwarvesAreDifferent Dwemer]] ruins.
*** The giant mushrooms of Morrowind make a return in the ''Dragonborn'' DLC. Tel Mythrin, a Telvanni tower in Solstheim, is a more traditional mushroom shape compared to the towers we saw in Morrowind.
* In the ''VideoGame/{{Warcraft}}'' series we first see giant mushrooms in ''VideoGame/WarcraftII: Beyond the Dark Portal'' on Draenor, the native world of the orcs, and these mushrooms provided the same lumber as trees. ''VideoGame/WarcraftIII'' and ''VideoGame/WorldOfWarcraft'' added other places with giant mushrooms growing there -- such as some dungeons and the Plaguelands. In [=WoW=]'s Outland -- the place that remained of Draenor after its [[ApocalypseHow destruction]] -- the only place where giant mushrooms grow is Zangarmarsh, some of these being large enough to have houses built on top of them and for a player to get killed by falling off one. In a later expansion's uncorrupted Draenor from an alternative timeline, there are several places with giant mushrooms.
* ''VideoGame/{{Diablo}}'' has a quest line where the player must retrieve a larger-than-average black mushroom.

-->'''Knuckles''': We have jungle mushrooms on my island too, but not ''this'' huge!
** ''VideoGame/SonicTheHedgehog2006'' had large mushrooms in jungle.

** ''VideoGame/MarioKart Wii'' has mushrooms big enough to drive a car on the caps.
* ''VideoGame/{{Metroid}}'':

* ''VideoGame/SpaceHarrier'': In Stages 3 (Amar) & 10 (Minia), giant psychedelic mushrooms fly at you at great speed.
* The Creator/{{Infocom}} text adventure ''VideoGame/{{Trinity}}'' had a land of giant mushrooms, each representing one [[UsefulNotes/NuclearWeapons atomic / nuclear explosion]].
* The Felucia levels of ''VideoGame/TheForceUnleashed'' and ''VideoGame/StarWarsBattlefront 2'' (and probably a metric shitload of other Star Wars game released around or after the prequel trilogy which likely as well feature the world of Felucia in some manner or another).
* ''VideoGame/DwarfFortress'' has [[BeneathTheEarth subterranean forests]] with "trees" like tower-caps and fungiwood, that are so large that they function as a source of lumber. An honorable mention also goes to the Plump Helmet, your staple food crop; by implication they could be anything up to the size of a television set.
%%* ''VideoGame/DonkeyKong64'': Fungi Forest.%%ZCE
* The Echovale Forest in ''VideoGame/GuildWars Factions'' features giant petrified mushrooms that are more than ornamental- they emit spores that afflict you with the annoying 'Stone Spores' condition.
* ''VideoGame/FinalFantasyX'' had Mushroom Rock Road, but the cliffs just resembled large mushrooms. Halfway there, at any rate.
* ''VideoGame/FinalFantasyCrystalChronicles'' had a dungeon called the Mushroom Forest, with giant mushrooms taking the place of trees.
* In ''VideoGame/TheSecretOfMonkeyIsland'', the area known as "The Caverns of Meat" had mushrooms that were slightly shorter than a person, and really wide.
* ''VideoGame/FallenLondon'': The series takes place in a huge, dark underground cavern, so, of course, mushrooms show up a lot.
** ''VideoGame/SunlessSea'':
*** Groves of giant mushrooms are fairly common as terrain decorations, and are visible in numerous areas of Unterzee when you sail close to the shores.
*** Demeaux Island is completely covered in a thick jungle of tree-sized mushrooms, providing cover to pirates, ambulatory carnivorous mushrooms of somewhat more reasonable size and other monstrous predators. The Iron and Misery Company has established an outpost on its shores to harvest the fungi -- the bolegus mushroom-trees make good lumber. The logging has little impact on the jungle -- the mushrooms grow back almost as fast as they're cut down.
*** The biggest mushroom of them all is the Uttershroom, which is large enough to have a small village on top of its cap. It's also surrounded by large mushrooms that at at least as big as your ship.
** In ''VideoGame/SunlessSkies'', the town of Hybras is located in an area of the Reach covered with titanic growths of fungus and mold. The enormous fronds and mushrooms easily dwarf your locomotive -- some of the shelf mushrooms are as big as city blocks -- and the great fungi that loom in the background are bigger still.
* ''VideoGame/LittleNemoTheDreamMaster'' had giant mushrooms in the first level. As mentioned above, they also appear in [[Anime/LittleNemoAdventuresInSlumberland the source material]].
* The dominant form of native life in ''VideoGame/SidMeiersAlphaCentauri'' is the enormous mass of Xenofungus, including an aquatic variety, which is incovenient rather than deadly (until you've researched the appropriate technologies). The same cannot be said, however, for the mind worms that lurk in the fungus...
* ''VideoGame/GearsOfWar2'' has mushrooms that are slightly shorter than Fenix, and some giant puffballs that might be fungi.
* One of the levels of ''VideoGame/FutureCopLAPD'' featured a part where you had to move across gigantic mushrooms growing in the sewers you were in to avoid getting damaged by what was probably corrosive fog covering the floor.
* ''VideoGame/IllusionOfGaia'' had a level consisting of huge mushrooms connected by big green vines. Because everything looked pretty much the same, it was something of ThatOneLevel.
* In the classic MMO ''VideoGame/EverQuest's'' expansion "Shadows of Luclin" you were on the moon. The moon's 'darkside' was literally that - it '''never''' got light. There were groves of mushrooms and even a giant mushroom rainforest.
* ''VideoGame/Lineage2'' has giant mushrooms in various areas of the world, some man-sized, others are big as buildings. 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 [[ThatOneBoss Orfen]], the [[AttackOfThe50FootWhatever fifty foot six-armed spider queen]] that hides in there.
* The deadliest peril in ''VideoGame/{{Repton}} 3'' is the rapidly growing fungus. Unless you block it off, it can cover entire ''levels''.
* The Myconid, which serves as a WarmUpBoss in ''VideoGame/WonderBoyInMonsterWorld''.
* ''VideoGame/PhantasyStarUniverse: Ambition of the Illuminus'' introduces Habirao Forbidden District on the {{Wutai}} Planet of Neudaiz, a place where mushrooms have grown massive due to a reaction from [[LifeEnergy photonic energies]] there.
* ''VideoGame/StarTrekOnline'': Some of the randomly generated planetary surfaces are basically giant mushrooms.
* Giant mushrooms are a common environmental feature in the ''VideoGame/{{Rayman}}'' series, particularly the Canopy level in ''VideoGame/{{Rayman 2}}''.
* ''Tass Times in Tonetown,'' an early Creator/{{Activision}} game had these in a few sections of the forest maze. Linger too long and the spores could [[HaveANiceDeath suffocate you]]. Of course, if you take a hunk of it, it's used to solve a puzzle later. You can also eat it. If you do, the game tells you that you [[MushroomSamba Timothy Leary walks in, laughs at you, and disappears]].
* In ''VideoGame/{{Okami}}'', an early dungeon has some teeny tiny mushrooms. They grow huge enough to jump on when exposed to sunlight (which, of course, would have the opposite effect on real mushrooms).
* ''Franchise/TheLegendOfZelda'':
** ''VideoGame/TheLegendOfZeldaSkywardSword'' features mushrooms that are the same size as Link. If you cut them with your sword, they regenerate in seconds. You can also get a makeshift potion substitute from them.
** In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', Hyrule Ridge is defined by forests of giant mushrooms.
* ''VideoGame/AmericanMcGeesAlice'' and its sequel ''Alice: Madness Returns''. Including giant flesh-eating mushrooms. (Well, technically, the mushrooms are normal-size; before encountering them, Alice is shrunken to very small size.)
* ''VideoGame/RunesOfMagic'', located just outside the Elf starter town & in a cave in the Human starter village.
* ''Whisper of a Rose'', in the dream world.
* ''VideoGame/{{Aveyond}}'', in a specifically Wonderland themed bit of land.
* ''VideoGame/SepterraCore''. Shell 7's Mold Forest, although the game doesn't say whether or not these are actual fungi or oversized plants convergently evolved to look exactly like giant fungi.
* ''VideoGame/{{Minecraft}}'' has the Mushroom Fields biome, complete with tree-sized giant mushrooms, ground covered by mycelium instead of grass, and "[[PunnyName mooshroom]]" cows. The player can grow their own giant mushrooms by using bone meal on a regular mushroom. They also appear in swamps (in the Pocket Edition) and in the [[TheLostWoods Roofed Forest]], where they contribute to the ever-present gloom. Huge mushrooms come in two varieties: brown with flat, wide caps and red with dome-like spotted caps.
* ''VideoGame/{{Terraria}}'' features an underground forest biome complete with tree-like mushrooms which can be harvested.
* ''VideoGame/{{Solatorobo}}'' has Visla, a continent full of humongous fungus and BigCreepyCrawlies.
* ''VideoGame/DarkSoulsI'' has mushrooms broad enough to be used as platforms in lower areas of [[BonusDungeon The Great Hollow]], [[MushroomMan as well as]] the mostly harmless Mushroom Children (watch that charging headbutt though) and the obscenely strong and durable [[MightyGlacier Mushroom Parents]].
* Several locations in the ''VideoGame/EarthBound'' [[GameMod ROM Hack]] ''VideoGame/{{Unearthed}}'' have mushrooms nearly twice the size of the protagonist. Since most of the game takes place underground though, and mushrooms often thrive in darkness, it doesn't stand out as much as some examples.
* One of the selectable biome types for planets in CivilizationBeyondEarth is Fungal, in which instead of plants, [[ExactlyWhatItSaysontheTin fungi dominate the planetary ecosystems]]. In particular, a gigantic (as in, three tiles' worth of space) specimen of fungus is found somewhere on every fungal map. Slightly smaller samples are scattered all over the planet as well, providing substantial food benefits to surrounding tiles.
* In ''Videogame/{{Evolve}}'' these appear in the jungle maps.
