First report of an unrecorded nematode-trapping fungus species Dactylellina candidum in Korea

Abstract

Dactylellina candidum, a fungus that captures nematodes by means of non-constricting rings and stalked adhesive knobs, was isolated from rotten wood in the Euiseong area, South Korea. This fungus produces 1–3 fusiform or clavi-fusiform conidia, which are 2–4-septate (mainly 4-septate) and sized 36.0–45.4 × 7.3–9.7 µm (L × W), at the conidiophore apex. This is the first report of Dactylellina candidum in Korea. This fungus should be considered a potential biological control agent for plant-parasitic nematodes. Key words: Dactylellina candidum, nematode-trapping fungus, non-constricting rings, stalked adhesive knob, unrecorded species.
