Summary

Two marine and 14 clinical isolates ofA. boydii and its byssoid phase,M. apiospermum, were compared with respect to their saline tolerance, morphological development, and sporulation on various commercial and compounded media. Isolates from sea-water and human infections were morphologically alike, and possessed similar saline tolerance. Most strains had salinity optima near 9‰, about the salinity of blood. Only marine isolates fruited well on Sabouraud's dextrose agar and other routine mycological media. On a medium containing wood and sea-water, and few soluble organics, 12 strains formed mature ascocarps or synnemata, or both. Low nutrient level media containing wood or cellulosic paper, with or without sea-water, were recommended for the propagation and conservation of sporulating cultures of many saprobic Ascomycetes and synnematous Fungi Imperfecti.
