Fungal armour has 3 pieces, which are created by using the Crafting skill to add fungal flakes to the corresponding mycelium web armour piece. 3800 flakes are required to make the total set; 300 for the visitors, 1000 for the leggings, and 2500 for the poncho.
Please note that all armour created with the flakes from the dungeon is degradable, and may be repaired by using a lot of flakes on the armour with a needle and thread in the inventory. Bob in Lumbridge will not repair the armour. The armour needs level 25 in Defence and Magic to be equipped.
Before the Evolution of Combat, fungal armour, along with grifolic armour and ganodermic armour, was the only armour in RuneScape that gave higher soak percentage in their own style than the style they were supposed to be strong against, in keeping with the combat triangle.
