Nineteen Stachybotrys alternans strains isolated from animal feeds, fodder or bedding and from grain for human consumption were tested for their toxin‐producing capacity on a mixture of wheat, oats and barley. Ultraviolet light was applied during isolation of the fungi. Nine out of the 19 strains were toxic to white mice in a feeding experiment of two week's duration. Five selected strains were also tested by the rabbit skin test and by the feeding test with guinea pigs. Clinical symptoms and patho‐anatomical pictures are described. The reason why S.alternans has been rarely found in grain is discussed.
