black soil blindness

black soil blindness

mycotoxicosis of cattle in northern Australia caused by grazing Astrebla spp. (Mitchell grass) pasture in which the seed heads and other parts of the plants are parasitized by coral-like fungal bodies produced by Corallocytostroma spp. Characterized by blindness, sudden death, rumenitis and nephrosis and its restriction to high rainfall periods on the black soil plains on which the grass dominates the pasture.
