Putative mycotoxin-producing fungi isolated from "alpataco" (Prosopis flexuosa) fruits

Fungi contaminant of "alpataco" (Prosopis flexuosa) fruits from "La Pampa province" (Argentina) were identified. Alternaria alternata and Sphaeropsis sapinea were the dominant species. Phoma sp., Nigrospora sp., Preussia minima, Cladosporium sp., Pithomyces chartarum, Epicoccum n...
