"Don't look now, but there's a humongous fungus among us!"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 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. 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 Beneath the Earth. This is usually considered a Plant Trope, even though fungi are not, you know, plants. Can lead to Fridge Logic issues if an entire planetary ecosystem is based on this trope, as even giant fungi can't produce oxygen like plants can.

In truth, the Temple's true patron was 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. (Kind of hard to feel sorry for a demon, but still, she was clearly the Lesser of Two Evils.)

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.
