If we reach curiously into the depth of the grotto to snatch a specimen of the shining objects, and examine the prize in our hand under a bright light, we can scarcely believe our eyes, for there is nothing else but dull lusterless earth and damp, mouldering bits of stone of yellowish-grey color! Only on looking closer will it be noticed that the soil and stones are studded and spun over with dull green dots and delicate threads, and that, moreover, there appears a delicate filigree of tiny moss-plants, resembling a small arched feather stuck in the ground. On looking into the interior of the cave, the background appears quite dark, and an ill-defined twilight only appears to fall from the center on to the side walls but on the level floor of the cave innumerable golden-green points of light sparkle and gleam, so that it might be imagined that small emeralds had been scattered over the ground. It prefers damp, but not too wet, mineral soils with a source of dim light, such as reflection from a pool of water, and so grows in habitats such as overturned tree roots, entrances to animal burrows and caves.Ĭoncerning the moss's common names, such as "goblin gold", Austrian Botanist, Anton Kerner von Marilaun wrote in Das Pflanzenleben der Donauländer in 1863: ![]() It is easily outcompeted by other mosses and plant species in open, brighter areas, but its ability to concentrate the available light allows it to grow in shady places where other plants cannot survive. Schistostega pennata is found in China, Japan, Siberia, Europe, and North America. A long stalk holds the egg-shaped capsule aloft. The fronds of shoots that develop from the persistent protonema are small (1.5 cm long) with opposing pairs of leaves. ![]() The little lenses have the capability of turning towards the light source to maximise the collection of available light. The chloroplasts absorb the useful wavelengths of the light and reflect back the remainder towards the light source, giving the moss a greenish-gold glow. The moss has adapted to grow in low light conditions by utilizing spherical cells in the protonema that act as lenses, collecting and concentrating even the faintest light. ![]() It is the only member of the family Schistostegaceae. Schistostega pennata, also called goblin gold, Dragon's gold, luminous moss or luminescent moss, is a haplolepideous moss ( Dicranidae) known for its glowing appearance in dark places.
