Mycorrhizal fungi of Douglas fir ( Pseudotsuga menziesii (Mirb.) Franco) in the South Island of New Zealand were studied using field observation of sporocarps, examination of mycorrhizas. and isolation of fungi from mycorrhizas. Sporocarps of Hebeloma crustuliniforme (Bull, ex St. Am) Quél, and Laccaria laccata (Scop, ex Fr.) Berk & Br. were the most commonly seen in the nursery but Rhizopogon parksii A.H. Smith and Suillus lakei (Murrill) A.H. Smith & Thiers were the most common in plantations. Mycorrhizas formed by H. crustuliniforme, Endogone flammicorona Trappe & Gerdemann, and Tuber sp. were found to be the most abundant in the nursery and those formed by R. parksii, S. lakei, and Tuber sp. the most common in plantations. Rhizopogon parksii, S. lakei and Tuber sp. were consistently isolated from mycorrhizas of trees of all ages. Suillus lakei appears to be a common mycorrhizal fungus of Douglas fir in the South Island of New Zealand, whereas this association is rare in the North Island.
