Ecological Indicator Information

A shade-tolerant/intolerant, submontane to subalpine, circumpolar club-moss (trans­continental in North America). Occurs on moderately dry to fresh, nitrogen-poor soils. Widespread on water-shedding sites in boreal, cool temperate, and cool mesothermal climates; its occurrence increases with increasing latitude. Common in open-canopy coniferous forests; often inhabits decaying wood, persists on undisturbed cutover areas. Grows with Hylocomium splendens, Pleurozium schreberi, Ptilium crista­castrensis, and Rhytidiadelphus loreus. An oxylophytic species characteristic of Mor humus forms.
