Abstract
An ultrastructural study of Sphaeromyxa balbianii has been carried out for the first time. The parasite was found in the gall bladder of Cep ola macrophthalma caught in the Catalan coasts (NW Mediterranean). The trophozoites of S. balbianii were polysporal plasmodia of big size (4 -6 mm) acid discoid shape. A variable number of plasmodia could be fou nd free inside each gall bladder. The spores, proved to be one of the most defining parameters at species level. There were straight and siz ed 15.82 x 4.84 mu m showing two polar capsules at the opposite ends. A discussion on the ultrastructure of the parasites as well as on the taxonomy of the genus Sphaeromyxa is provided.
