Mushrooms of the Bitter Coast Journeyman Report from Ajira Ajira studies four common mushrooms in Vvardenfell. Luminous Russula is a toadstool like mushroom with a brown spot on top. All Russula has strong odors, but Luminous Russula much stronger. Russula can be poison if not prepared right. When mixed with pearl dust it makes very good potion to breathe under the water. Violet Coprinus is a tall toadstool that glows in the night. Coprinus also is poison if mixed wrongly like if you mix with Russula. Coprinus mixed withscales lets Ajira walk on the water instead of under the water. Much better.
