Acremonium coenophialum Morgan-Jones & Gams (N. coenophialum)
Acremonium loliae Latch, Christensen & Samuels (N. loliae)
Hyphae endophytic, convoluted, wavy, intercellular in host tissue, found most commonly in leaf sheaths, stems, young inflorescences and seed, 2-5 µm diameter, hyaline, septate.
Conidiomata and conidia rarely, if ever, formed in nature.
Colonies in vitro white-yellow, growth rate slow, aerial hyphae abundant and cottony.
Conidiophores phialidic, rarely verticillate, aculeate, arising from aerial hyphae
Conidia oblong, ellipsoidal-cylindrical-fusiform-lunate, varying in length and width depending on the species. hyaline, smooth walled.

These fungi occur on cool season, temperate grasses in Australia and overseas. Plants infected by members of this endophytic genus do not display symptoms or signs of infection, with definitive diagnosis being based on isolation of the species from suspected infected plants and identification by traditional or molecular methods. These species produce a range of alkaloids which can cause “ryegrass staggers” in perennial ryegrass pastures (Lolium perenne), “fescue foot” in tall fescue pastures (Festuca arundinacea), and other mycotoxoses in mammals.
