Fungus

A Fungus (plural fungi) belongs to the kingdom of eukaryotic organisms. They are distinguished by being icky and gross. While in some ways similar to plants, in particular because of their root systems (called hyphae), fungi are in fact heterotrophic organisms which means that they grow out of yucky stuff like old food, rotting wood, and smelly feet because they cannot photosynthesize like plants. Yeasts, molds, and mushrooms are examples of fungi. The study of fungi, in addition to being absolutely disgusting, is called mycology.

General features and nastiness

Different types of fungi are adapted to live in nearly any environment, but they seem to have a creepy preference for refrigerators and all kinds of gross-smelling things. There are an estimated 1.5 million fungal species in the world, which is way too many considering that even one is more nauseating than anything needs to be.

Just look at it! Who would want to eat that thing? It's obviously fatal.

Ew, gross!

Many species of fungi are cultivated by humans for various purposes. Some freaks actually like to eat mushrooms, even though it's totally obvious that mushrooms aren't meant to be eaten, even the ones that aren't poisonous. Some varieties of cheese are made with a mold fungus to give it a particular texture and flavor–one of supreme nastiness. Penicillin is derived from a fungus, as are many other antibiotics, but frankly it would be less icky to just deal with the bacteria; at least we can't see those.

Ecological role

While often ignored or unseen in their natural environment, fungi are everywhere, creeping all over stuff that hasn't been properly sprayed down with bleach. They are critical decomposers of organic matter, but there's no goddamn way I'm going to let them grow on my corpse when I kick the bucket. I want to be turned into ash at the crematorium.

Humans and Fungi

We as people like some fungi to eat or use for medicinal hallucinations. However there are plenty of bad mushrooms who come without a healthy label. These are known as Toadstools. Trips with those end in death.

Humans are prey to fungi infections. These animals like moist regions and so can be found under toenails, feet, hands and under armpits. The worse case sufferers get genital fungi which is no laughing matter! They also spread on faces and form beards.

Last 'living' being

When everything else dies on the planet, the humble mushroom will rule supreme. They will have plenty of rotten bodies to feed on.
