Ectomycorrhizal species associated with Pinus radiata in New Zealand including novel associations determined by molecular analysis.

Ectomycorrhizal (ECM) associates of the exotic plantation species Pinus radiata were investigated above and below ground over two years in the North Island of New Zealand. ECM species were identified using morphological and molecular (restriction fragment length polymorphism and DNA sequencing) analysis. Eighteen ECM species were observed fruiting above ground; 19 ECM species were identified below ground.
