Glittering Wood-moss

Appearance

It is generally olive green, yellowish or reddish green in colour, with reddish stems and branches. These often form branches up to 20 cm. long, with current year's growth starting from near the middle of the previous year's branch. This produces feathery fronds in steps. It is possible to estimate the age of a plant by counting the steps - a new level being produced each year. This form of growth enables the species to "climb" over other mosses and forest debris that falls on it. It is shade-loving, grows in soil and humus and on decaying wood and often forms mats with living parts growing on top of older, dead or dying sections. Further south, the plants are larger with several steps; further north, in the arctic tundra, the plants are smaller with few steps.

Habitat

Occurring widely in the boreal forests, this plant is often found on forest floors even in relatively harsh northern latitudes. In Canada, for example, according to C. Michael Hogan the Black Spruce/Feathermoss climax forest often occurs with moderately dense canopy featuring a forest floor of feathermosses that include ''H. splendens'', ''Pleurozium schreberi'' and ''Ptilium crista-castrensis''. Experiments simulating global change with increased nutrient deposits and warming indicate that increased nutrient deposits and climate warming may have negative impact on growth of Hylocomium splendens.
