Foliaceous lichens on granite in Corsica. Saxicolous foliaceous lichen Umbilicaria pustulata (=Lasallia pustulata) - sometimes abundant on rocks, eaten in Canada as rock tripe. The yellow foliaceous lichen with isidia is probably Xanthoparmelia conspersa.

Pulmonary lichen (Lobaria pulmonaria) in the Vercors. A large foliaceous lichen - one of the largest in Europe - whose thallus commonly exceeds about 30 cm. Like all lichens, it is a lichenised fungus, and like most of them it belongs to the ascomycetes group. Its membership of the cyanolichen category, fungi associated with cyanobacteria, makes it a particularly sensitive organism to atmospheric pollution. It is therefore a species in decline in many regions and has been chosen as a health index for French forests. Ambel forest, Vercors NRP, France

Orchilla lichen (Roccella canariensis) on the island of El Hierro (Canary Islands). Roccella canariensis is a fruticose lichen of the Roccellaceae family known as Orchilla from which a natural dye used for the colour purple is extracted (orcein). It grows on the Canary Islands, on cliffs exposed to the trade winds, and was particularly prized by the Romans and by Genoese and Venetian cloth merchants in the 15th century. It was one of the main historical exports of the Canary Islands. El Hierro
