You conjure and hurl a ball of toxic mushroom spores at a point of your choice you can see within range, where it bursts into a 15-foot radius cloud. The area of the cloud is heavily obscured, and when a creature enters the cloud for the first time on its turn, or starts its turn there, it must succeed on a Constitution saving throw or take 2d10 necrotic damage, 2d10 poison damage, and be poisoned until the start of its next turn. On a successful save, a creature takes half as much damage and is not poisoned. A strong wind of 10 miles per hour or more can disperse the cloud early.
