Ecological Indicator Information

A shade-tolerant/intolerant, submontane to montane, Western North American parasite distributed more in the Pacific than the Cordilleran region. Occurs in cool temperate and cool mesothermal climates on fresh to very moist, nitrogen-medium soils; its occurrence decreases with increasing elevation and continentality. Sporadic in the mossy understory of coniferous forests on water-shedding sites. Characteristic of moist coniferous forests.
