Star-tipped reindeer lichen

The star-tipped reindeer lichen is a large vertical-growing lichen that forms grey-yellowish cauliflower-like heads.

The plant forms dense groundcover in dry heath- and rocky forests as well as in fell landscapes. As a continental species, it doesn’t grow often in the archipelago. It is found across Europe, North America and Asia.

In the past, the species was used in window glazing to collect moisture and as an herbal remedy in foot baths. It was also used to treat skin infections due to its antibiotic properties. Today, it is used as an ornamental plant.

Because it regenerates very slowly, harvesting the star-tipped lichen is subject to permission. Star-tipped reindeer lichen has adapted to live in low-productive cliff and bare rock areas, which are excluded from forestry operations.
