Ynghylch

Goblin's gold is a luminous moss that grows in dark places. It can be found in rocky crevices, cave entrances, old stone ruins and even rabbit burrows. It has lens-like cells, which concentrate any light that hits them onto the chloroplasts. This means that the moss can photosynthesise even in very dim light. This allows goblin's gold to thrive in areas that are too dark for other plants to survive.

As a side effect, some light is reflected, causing the moss to give off a shining golden-green glow. Goblin's gold can grow into large colonies, covering cave walls and floors. This shimmering display has given rise to the evocative nickname of goblin's gold, or sometimes dragon's gold.

What to look for

The golden-green glow of this moss makes it instantly recognisable when found in dimly lit places. It develops shoots that resemble tiny palm fronds.

Where to find

Predominantly found in the west of Britain, especially southwest England.
