ABSTRACT: The octocoral disease aspergillosis is caused by the terrestrial fungus Aspergillus sydowii. The possibility of secondary (horizontal) transmission of aspergillosis among common sea fans Gorgonia ventalina would require waterborne transmission of hyphae and/or spores. A laboratory filtration experiment confirmed that fungal hyphae and spores were shed into the water by infected fans. This suggests that secondary infection might be possible in this species. It remains to be determined whether healthy fans actually develop aspergillosis after contact with hyphae-laden water.
