Sporothrix schenckii Isolated from Edible Black Fungus Mushrooms.

Sporothrix schenckii , a fungus which is pathogenic to humans, was recovered from imported desiccated black fungus mushrooms [ Auricularia polytrichia (Mont.) Sacc.] usually used in preparing Far Eastern cuisine. Identification was based on microscopic and gross morphology, dimorphism at 25 and 37°C and reactivity with fluorescein-labeled antibodies specific for the yeast-cell form of the fungus. This is the first known report of S. schenckii in or on edible mushrooms.
