The authors report the finding in Southern Spain of an apparently rare fungus: Ciboria aestivalis (Pollock) Whetzel (Sclerotiniaceae) growing on mummified quinces (Cydonia oblonga Miller). Originally described from apples (Malus sp.) in the United States, the species has also been reported on other pomaceous and stone fruits in Australia. A recent report from France is based on a misidentification, whilst a British reference to “imported fruit” refers to mummified quinces brought from Australia. The inoculation of various fresh fruits produced mummies which developed apothecia, also on blackened pips from a mummified apple, whilst stromata formed in P. D. A. cultures. The apothecia are described in detail and illustrated, including the type. Its generic placement in the Sclerotiniaceae is discussed.
