Abstract
Lewia hordeicola with Alternaria anamorph was isolated from barley grains in Norway. The fungus is homothallic. It produces fertile ascomata on synthetic nutrient agar (SNA) after long incubation at 4 C in the dark. On PCA its anamorph resembles members of the A. infectoria species group. On SNA L. hordeicola differs from the latter in the shape and size of ascospores, the conidial sporulation patterns, and the shape, size, septation and roughness of conidia. A key to currently known Lewia species is included.
