Lichen by Candlelight

Believe it or not this bright yellow lichen is called Candelariella reflexa, lit beautifully by the sun, it has produced candlelight (excuse the slight spelling misnomer!) and so I’ve selected this photo for Becky at the Life of B‘s #JanuaryLight square photo challenge.

Whilst lichens are non-parasitic and therefore not harmful to the plants they grow on, they are of invaluable use to invertebrates for food and shelter. A lichen consists of two more organisms, fungus and algae, who live and grow together in a symbiotic relationship. Lichen are pollution sensitive and so their presence and rate of growth are an indicator of air quality. For more information about lichen, there’s a really fascinating article about this often maligned organism on the Woodland Trust website.
