Two types of lichens; foliose and crustose
The two lichens you see in the pictures might be: 1) A shield lichen a type of foliose lichen 2) A crustose lichen (maybe a goldspeck? Or a candleflame?)
General Biology: Lichens are a symbiotic relationship between fungi and either green algae or cyanobacteria. The fungi is the visible part and the algal component is microscopic. Lichen are considered to be in the Kingdom Fungi. The relationship is called mutualism where both organisms benefit since the fungi provides shelter and protection while the algal component provides food. Lichens exhibit a vast array of beautiful pigments that play a role in protecting them from varying degrees of UV light. Lichens also play a critical role in soil formation since they secrete acids which help decompose rocks over time.
Human Interactions: Lichens have various medicinal uses along with being used to make dyes. Some cultures consider them to have magical properties.
Ecological Items: Lichens thrive where the air is clean and thus can indicate degrees of air pollution. Some organisms eats types of lichens and birds can use them as nesting materials.
