Recently, we isolated a fungus from blue fescue (Festuca glauca Lam.) and from a hybrid fescue (F. ovina L. x F. glauca). It was identified as Acremonium typhinum Morgan-Jones & Gams after comparison with other isolates of A.typhinum and Acremonium spp. A typhinum is an anamorph of Epichloe typhina (Pers. ex Fr.) Tul., which is known to commonly produce a stroma or "choke" symptom on grass hosts. Some species of Acremonium impart insect resistance as well as other benefits to grass hosts and consequently have been of much interest in recent years (2). Saha et al in 1987 reported the presence of an unidentified Acremonium-like fungus in blue fescue (1). To our knowledge, this is the first isolation and identification of an Acremonium endophyte from blue fescue. |
