Symptoms of red leather leaf of oats were widespread and severe in spring 1988 on autumn‐sown oat crops in the south and east of Ireland. The disease was characterized by grey‐brown elliptical lesions, developing into light‐grey eyespots surrounded by dark borders. Plants were stunted and showed reddish‐brown foliar pigmentation extending beyond the lesions. Spermospora avenae was isolated and shown to be pathogenic to oats. Cultural characteristics of the pathogen on several agar media are described. The disease has previously been reported only from the USA, Turkey and Australia.
