This contributes to the long-term weathering of rocks for soil formation, and more broadly to the million-year geologic cycle of mountain building and erosion. Fairly frequent in Leicestershire and Rutland. Thesis. Comprised of a fungus that has partnered with one or more organisms from a different kingdom, 14,000 identified lichens have mastered the art of survival in the most inhospitable of habitats from hot, dry desert to frozen tundra. Usnic acid is found primarily in the top layer of the fungus along with another chemical called altranorin just above the area where the algal bodies are concentrated. There is good reason to suppose that some form of union like a lichen may have come about by chance and was then promoted by survival.

Photo: Gary Miller. caperata is Latin for wrinkled. Alga are capable of producing food by photosynthesis but fungi cannot produce their own food. The very similar Flavoparmelia baltimorensis grows mainly on rock and has globose, pustular outgrowths (somewhat similar to isidia) on the upper surface of the lobes, but does not produce granular soredia. Greenshield lichens often cover broad expanses of rock and tree surfaces to the extent that long term effects come into question. The rounded lobes, measuring 38mm (0.10.3in) wide, usually have patches of granular soredia arising from pustules. The lobes of the thallus may be smooth, but quite often have a wrinkled appearance especially in older specimens. #080: Flavoparmelia caperata, The Common Greenshield Lichen.

The exceptions are the greenshield lichens that spread their leaflike (and tongue-like) lobes outward and onward, oblivious to the reduced light and frigid temperatures by which the rest of the forest is constrained. Parmotrema hypotropum, (Powdered Ruffle Lichen), and Flavoparmelia caperata, (Common Greenshield Lichen), are both commonly found here in Virginia. that the inside is made of pure white cottony strands of fungal [2].

Consequently, lichen hyphae penetrate rock surfaces to depths of several millimeters seeking water, and, depending on the type of rock, minerals as well.
