COLLECTION AND IDENTIFICATION: Collected by D.M. Goodman (PHDSN28/EM3) 9 November 1992, near the Koksilah River on Vancouver Island, 48o39’20” N by 123o45’50” W; described by D.M. Goodman. Identified by D.M. Goodman: matches description of P. croceum + Fagus sylvatica by Agerer (1993); P. fallax is the only golden species of Piloderma in North America, and is synonymous with P. bicolor (Peck) Jülich sensu Jülich and P. croceum J. Erikss. & Hjortstam (Ginns and Lefebvre 1993, Larsen 1983, Smith et al. 1996, Stalpers 1984); accessioned in herbarium as DAVFP 25169.
ECOLOGY: One of the most abundant ectomycorrhizae found in old-growth (288, 441 year) and mature (87, 89 year) stands of Douglas-fir at two sites in the Coastal Western Hemlock dry maritime (CWHxm) biogeoclimatic zone, site series “03 – FdHw salal” on southeastern Vancouver Island (Green and Klinka 1994), elevation 450-630 m; twenty-one collections of 600 tips total were made almost exclusively from decaying wood, some tips in fragmented litter, not found in the mineral soil, active in both May and November.
