It is the first and only report of any Aplanes de Bary to cause disease on any fish. A. braunii was found to be a virulent parasite ofA. cobojius causing cotton-wool disease involving the skin and fins. The hyphae also penetrated into the tissues of the infected fish and all of them ultimately died.This revised version was published online in October 2005 with corrections to the Cover Date.
