Abstract: The material consisted of 1035 samples of ripening cereals gathered from 119 1ocalities in southern Finland and 32 samples of Agropyron repens. Wojnowicia graminis (Me Alp.) Sacc. & D. Sacc. (Deuteromycotina: Sphaeropsidales) was found in 32 cereal samples from 22 localities. The fungus was fairly common on Triticum aestivum (winter wheat), in frequent on Secale cereale and Hordeum vulgare, and absent from Avena sativa. It was recorded on six samples of Agropyron repens from six localities. W. graminis causes symptoms resembling the take-all caused by Gaeumannomyces graminis (Sacc.) Arx & Olivier. In fields in southern Finland, W. graminis appears to be rather rare, sparse and of negligible pathogenic importance.
