Short description: Reproductive structure of a fungus
Light microscopy of Puccinia graminis with an aecium releasing its aeciospores through the broken leaf surface. A=Aeciospore, B=Aecium. Scale bar = 0.1 mm

Aeciospores are one of several different types of spores formed by rusts.[1][2] They each have two nuclei and are typically seen in chain-like formations in the aecium.[3]
