SUMMARY
Five ericoid mycorrhizal fungi were cultured on acidified potato-dextrose agar with or without the mycophagous nematode Aphelenchoides bicaudatus. Nematode parasitism destroyed aerial hyphae and limited growth of all isolates to one-half to two-thirds the mycelial areas of nonparasitized mycelia. Hyphal fragmentation was also evident. Results suggest that parasitism of endomycorrhizal fungi by mycophagous nematodes restricts mycorrhizal development and may limit nutrient uptake by mycorrhizal host plants.
