...ginosum, also called "Geyser's Dichanthelium," for fungal colonization. They found what may be a new species of the fungus Curvularia that survives only in temperatures greater than 98 degrees when it associates with plants.

While soils are contaminated both through natural occurrences of arsenic and spills and drainage from chemical and manufacturing plants, by far the ......ummer in some parts of the state and triggered the fungal growth, Whitlock said. Fumonisin can cause leukoencephalomalacia (leuko) in horses, a fatal necrosis of the brain; after an animal has the symptoms, recovery is unlikely.
