Reindeer Moss

Cladonia rangiferina

Despite its name, reindeer moss is actually a lichen (in fact it is also known as ‘reindeer lichen’).

Composed of many light and dainty branches, it grows in cushion-like tufts. When dry it can be quite brittle but once wet it becomes somewhat sponge-like.

Where it grows

Reindeer moss is usually found on moors and heathland, often growing in pockets of soil attached to rocky outcrops.

Best time to see Reindeer Moss

Reindeer Moss can be spotted all throughout the year.

Something you might not know

The only naturalised reindeer in the UK are found in the Scottish Highlands where they live for much of the year on reindeer moss.

String-of-sausages Lichen

Usnea articulata 

  • Grey-green tassels of up to 1 m hanging down or draped across the substrate but rarely anchored to it.  
  • Main stems have inflated sections which are pinched at intervals, and so resemble a string of sausages. This is a key feature to look for as there are other pendulous Usnea species but none have this characteristic.

Habitat

It is most common in the south west’s temperate rainforest zone. 

Favouring well-lit conditions and dry, open situations, it is most often found in tree canopies or on lower branches where trees are well-lit, in woodland or on scattered trees in open moorland. You can also find it on the ground after stormy weather. 

Similar species

Other large, bearded lichens include Usnea ceratina, Usnea dasopoga and Usnea hirta but these lack the sausage-like lobes. 

Did you know

  • It is a Section 41 species which means that it is considered of “principal importance for the conservation of biodiversity in England” under Section 41 of the Natural Environment and Rural Communities Act (2006).
  • A clean air indicator, rare outside of south-west England’s rainforest zone. Highly sensitive to sulphur dioxide pollution, it was once much more widespread in Britain but now appears to be making a comeback, perhaps due to improved air quality and a warming climate. 

Distribution 

Largely restricted to south-western parts of the UK with most records in south-west England.
