Abstract

Dactylella pseudoclavata that captures nematodes in adhesive networks was isolated from nematode-infested strawberry plants from Andong, Korea. It produces obclavate, 0-1 septate conidia, $30-40{\mu}m$ long and $8-11{\mu}m$ wide, with round distal ends and bases shaped like bottle-necks. The conidiophores were simple, occasionally branched, $150-300{\mu}m$ long, producing 1-4 conidia at the apex. Chlamydospores were abundant, intercalary or catenulate, yellowish to brown, globate or subglobate, wart on the surface, $30-35{\times}25-30{\mu}m$ in size. This is the first report of Dactylella pseudoclavata in Korea.
