The distribution of nematophagous fungi in the maritime Antarctic
Endoparasitic and predatory nematophagous fungi are widely distributed throughout the maritime Antarctic, being recorded along the Antarctic Peninsula as far south as 68° S. Fungi were recorded from 71% of the sites examined with Cephalosporium balanoides and Dactylaria gracilis being the commonest...
