Caloplaca haematites

Caloplaca haematites is a species of lichen belonging to the family Teloschistaceae. It has mainly been reported from Europe but is also found in other parts of the world. It was reported in the UK media in 2011 because it was thought to have been extinct in Britain, but was rediscovered after 122 years.

Caloplaca haematites grows as an epiphyte on trees. A study on Kos Island reported Caloplaca haematites from the trunks of Melia azedarach and Robinia pseudacacia trees where it grows along other the other lichens Catillaria nigroclavata, Rinodina colobina and Rinodina exigua.
