Terresfungus

"This fungus has taken another path. While still capable of infecting creatures, it has actually began taking to land, where there is less fungus competition to grow. Although not as advanced or efficient as other forms of photosynthesis, fungi exposed to sunlight will take some of the energy and turn it into nutrients."
