Abstract Young barley plants at the two tiller stage were inoculated with a suspension of Asco- chyta phyllachoroides Sacc. & Malbr. f. melicae Fautrey conidia. After 14 days, apparently healthy leaves were removed, surface sterilised, and incu- bated on malt extract agar. A. phyllachoroides f. melicae was successfully reisolated from these leaves. The teleomorph Didymella phleina Punith. & Arsvoll, known to occur overseas as a pathogen of barley and other grasses, developed ascomata in vitro. This is the first record of D. phleina in New Zealand.
