FACT: Its common name comes from its unique protonema, which luminesces yellow-green when reflected with light. 

FACT: The common name can be deceiving as it can range from red to pale green in colour. Like other Sphagnum species, it makes its environment acidic via a cation exchange mechanism and can store 30 times its mass in water due to hyaline cells containing pores.

FACT: Ability to grow in acidic soil of disturbed banks. Perigonial heads are present in male gametophytes which form a splash cup mechanism for asexual reproduction to occur.

FACT:  It has a white pleated conical collar instead of the typical arthrodontous teeth usually seen in Bryopsid mosses. When raindrops come into contact with the capsules of the hygroscopic pleated collar, a rapid ejection of spores into the environment occurs! Above is a SEM image of its hairy calyptra.

FACT: As its name implies, its leaves are greatly contorted when dry. This response to dessication is a result of its relatively low cuticle content in leaves, causing them to have an exaggerated response.

Fact: Ability to grow in a variety of environments, including nutrient poor soils and snowy limestone pavement. Their common name refers to the relatively high altitude habitats that they can be found in, including montane and alpine areas.
