Cladosterigma is a fungal genus in the family Gomphillaceae. It is monospecific, comprising the single species Cladosterigma clavariella. The fungus is a hyperparasite: it grows on living leaves of myrtle relatives (genus Eugenia) where it parasitises a plant-pathogenic fungus in the genus Phyllachora. It is known only from an asexual state that forms conspicuous, yellow, branched synnemata (bundles of spore-bearing filaments) erupting through the leaf surface.
