Fungus

A fungus (NaN undefineds) was a type of vegetation that included mushrooms, toadstools, and molds.

Description
Some species of fungi were bioluminescent, but these were rather rare. They were more common in the Upperdark than the Middledark.

Habitats
Fungi were most abundant in Toril's Underdark, where they and other vegetation received nourishment from the ambient faerzress. Areas particularly diverse in fungi included Fluvenilstra and Gduar's Garden.

History
The year 238 DR was known as the "Year of Many Mushrooms." During this time, prevalent damp weather and rotting diseases all across northern Faerûn promoted rampant growth of mushrooms. Trade in harvested mushrooms and mushroom-related products (especially fried ones in salted gravy) became prevalent. And reports of myconid sightings became more common.

Varieties
Thousands of species of fungi existed on Toril. Some of the known fungi on the planet included the following:
 * Acorn truffle : A species of edible fungus found along forest beds and favored by many wild beasts.
 * Ascomoid : A very large, spherical fungus that typically rolled around and tried to crush its prey while spewing streams of spores out from its orifices.
 * Araumycos : A very large fungal growth that lived in the Upper Northdark.
 * Barrelstalk : A barrel-shaped fungus that usually held potable water but turned poisonous at maturity.
 * Bluecap : Common in the Underdark. It could be ground into flour and baked into sporebread.
 * Blushcap : A red and white mushrooms made famous by nursery rhymes.
 * Bonecap : A species of foul and acidic mushrooms that fed on grave rot.
 * Browncap : An edible wild mushroom, staple of dwarven cuisine.
 * Bullywug trumpet: A sour-tasting edible mushroom that flourished in dark and damp places.
 * Crag mushroom: A fleshy edible mushroom with healing properties.
 * Dragon egg : A medicinal subterranean mushroom.
 * Funguswood : A common mushroom used as a wood substitute and sometimes as a savory spice.
 * Frosted mushroom: A species of frost-covered fungus that released icy cold spored in a burst when squeezed.
 * Gas spore : A balloon-like, toxic fungus that bore a resemblance to beholders.
 * Glowcap : A easy glowing mushroom from underdark, and a valuable trade commodity.
 * Greensleep : A poisonous fungus found in the Moonsea area.
 * Morel : A species of edible fungus popular in Cormyr.
 * Nightlight : A naturally bio-luminecent fungus that grew in Underdark and could be used as a temporary source of light by travelers.
 * Phantom fungus: A type of fungal predator with innate invisibility.
 * Phycomid : A type of fungus that reproduced by infecting other organisms with their spores and gradually overtaking their bodies.
 * Rogue's morsel : A species of edible forest mushrooms from the Western Heartlands.
 * Swarming toadstool : A species of clustering parasitic mushrooms often found swarming bigger fungi.
 * Tessadyle : A stringy fungus common near mind flayer colonies. Primarily used for clothing.
 * Timmask : A hallucinogenic giant mushroom also known as the devil's mushroom that grew in Underdark.
 * Violet fungus : A fungus typically used by treants for protection, they could grow to the size of a human.
 * Zabou mushroom : A species of Chultan mushrooms with poisonous spores that caused severe itching.

Usages

 * Some bioluminescent fungi that grew in the Underdark were quite prized by alchemists on the surface.
 * Mushrooms made up the bulk of the diet of the inhabitants of Skullport. These mushrooms were sourced from mushrooms farms in small outlying caverns and other levels of Undermountain.
 * Fungi, especially those purposely planted as beds or forests, had a wide variety of uses for drow depending upon their species. Being used as a source of light, food, fiber for weaving, various medicines and oils, or a combination of these.
 * Some drow communities planted beds or even forests of fungi to dispose of their offal and sewage at. Some of these had the waste carted to them, others were at the ends of minute sewers, or were planted downriver along a riverbank. The last type were tended to by drow being punished, slaves, and sometimes even driders.
