Fungi

In lightless caverns and fey forests, fungi appear in every color and shape. Some grow to prodigious size, choking pathways or forming looming fungal forests.

Self-Propagators. Fungi do not need sunlight to flourish. They grow in any available organic matter, including bodily waste and corpses. Fungi provide many necessities to underground dwellers: food, fuel, alcohol, and even phosphorescent lighting. Common fungi reproduce by ejecting spores, which are carried on breezes or cling to the bodies of passing creatures. Monstrous fungi treat other life forms as food and hosts for expansion: they have a remarkable variety of ways to infest, infect, and devour more mobile creatures.
