The fungao looks like a giant mushroom (hence its name of zoraï origin which means precisely “mushroom”). Matis botanists suspect that it is actually a plant that lives in symbiosis with several types of microscopic fungi. The plant part ensures photosynthesis even in the tenuous light of the Prime Roots while the fungi draw forth the nutrients contained in the soil.
The fungao has two modes of reproduction: one, sexual, assured by the plant that flowers on the outgrowths present on the periphery of the volva; the other, asexual, carried out by the animals that nibble the fungao and spread by their droppings the spores of fungi.
Its firm and nourishing flesh is eaten by homins once it is peeled (the surface layers being infected by pathogenic bacteria).
