Type: Mycorrhizal Fungi; Description: Sporocarps globose to subglobose at first, lobed and convoluted when mature, white at first, becoming buff to orange brown, 5–20 mm in diameter; often found growing around small sticks or needles in the litter which become embedded in the sporocarp; peridium thin, often evanescent. Gleba white at first, becoming salmon pink to orange brown. Zygospores globose to ellipsoid, 0-septate, 50–120 × 40–100 μm, deep yellow to orange, enveloped in a spirally-wound hyphal mantle; mantle 5–20 μm thick, usually composed of a single layer of hyphae encircling each spore, lateral walls of adjacent hyphae coalescing to form flame-shaped projections.

Distribution: Waikato, Bay of Plenty, Taupo, Gisborne, Nelson, Buller, North Canterbury, Mid Canterbury, South Canterbury, Otago Lakes, Dunedin, Southland.; 1st Record: Chu-Chou & Grace (1979).

Significance: Shown experimentally to be an ectomycorrhizal partner of Pseudotsuga menziesii (Chu-Chou & Grace 1979) and of Pinus radiata (Chu-Chou & Grace 1984). Mycorrhizae formed by this fungus have no mantle but the Hartig net is well developed. Improvement of rates of early growth in P. radiata seedlings did not persist to the end of the first growing season (Chu-Chou & Grace 1984).; Host(s): Pinus radiata, Pseudotsuga menziesii.
