Fungus Magic

Fungus Magic (菌類の魔法, Kinrui no Mahō), alternatively known as "Mushroom Magic" (茸の魔法, Kinoko no Mahō), is a Caster-type Magic that involves the manipulation of "spores" and fungi in order to control the "power of mushrooms".

Description
Fungus Magic's main purpose is control over fungi, or mushrooms as they are most commonly known. This allows the user to instantly grow mushrooms of large size, ones that are unseen in nature. These fungi can be sprouted in seconds, by breathing out "spores" onto the ground, or by directly controlling the earth, spreading spores to the area in order to sprout the mushrooms. The mushrooms, being magical in nature, are much stronger than normal mushrooms, being capable of being effective barriers, or even used for offense, striking a target when summoned. In addition, the mushrooms can be grown on living organisms, but only on corpses, causing them to decompose, eventually turning the decomposing corpse into a mass of mushrooms in a matter of seconds.

Interestingly, it is possible to produced edible mushrooms using this magic, as a means of nutrition, and are noted to tasting identical to normal mushrooms, since apparantly they can be chewed easily if not used for combat purposes. It is also possible to produce various kinds of fungi, including ones used for medical treatment, or poisonous mushrooms, among other kinds.

One crucial weakness of Fungus Magic is its natural weakness to any fire-based magic, burning easily from flames, catching fire and burning to a crisp. This makes them almost useless against any fire mage, difficult, but not neccesarily impossible.

Trivia

 * Fungus Magic is inspired by En's magic from Dorohedoro.
