Mycotoxins formed by Neotyphodium species, ergovaline and ergovalinine are the most common toxins. Others include ergine, erginine and clavine alkaloids such as argoclavine. These toxins are found in fescue that is infected with Neotyphodium species, however these toxins are less toxic to animals. Neotyphodium species are also capable of producing lolitrem B, which does cause issues to livestock when ingested (see ryegrass staggers).
