Fungal Festerings: Cavern Habitat (2007)

From Introduction:

While deep, dark underground areas usually provide shelter, a stable temperature, and quite often a source of water they often tend to lack in other things that living creatures need to thrive. A light source would be nice, a continual offering of edible food would be great, and fresh, clean air to breathe is most desperately needed. But, beyond magic, how can one acquire such things underground? The answer is fungi.

This edition of Fungal Festerings provides six different fungal growths that make caves and caverns a bit more habitable.

This product is an expansion of The Tome of Arcane Mycology.
