Wu H. Y., Kim D. G., Ryu Y. H & Zhou X. B. (2012) Arthrobotrys koreensis sp. nov., a new nemato-de-trapping species from Korea. – Sydowia 64 (1): 129–136.

Arthrobotrys koreensis, a nematode-capturing fungus with adhesive 3-D networks was isolated from soil around the roots of Dystaenia takeshimana (Apiaceae) on Ulleung Island, Korea. It has monoseptate, obovoid conidia with a wide distal cell, measuring 18–30 × 9.2–16.7 µm, not or slightly constricted at the septum. Conidiophores are often unbranched and 150–400 µm in height, bearing 1–5 conidia on short denti-cles at the apex.
Keywords: sp. nov., adhesive network, taxonomy, molecular phylogeny.
