Abstract
Lichens are a life-form composed of fungi growing in symbiotic union with algae (Howe and Armitage, 2002). Lichen pigments play many important physiological roles, while their brilliant colors provide considerable aesthetic enjoyment(Howe and Armitage, 2003). The versatile array of lichen upper surface have been studied by using scanning electron photomicrography (Armitage and Howe, 2004). Lichen algae and fungi are woven together forming "sues" that resemble the tissues of unrelated "higher plants" in general fashion (Armitage and Howe, 2006).
