Lecanora muralis was found on the rock along coastal line during the field trip in Jeju island in 2006. Thallus crustose, placodioid, closely adnate, forming orbicular patches; upper surface grayish green, glossy; central lobes areolate, marginal parts plane, edges thin pruinose; lower surface ecorticate; apothecia sessile, lecanorine type, exciple dense and intact when young, and disc plane, b...

BACKGROUND The aim of this study is to investigate in vitro antioxidant, antimicrobial and anticancer activity of the acetone extracts of the lichens Cladonia furcata, Lecanora atra and Lecanora muralis. METHODS Antioxidant activity was evaluated by five separate methods: free radical scavenging, superoxide anion radical scavenging, reducing power, determination of total phenolic compounds an...

Lichens, a symbiosis of fungi and algae, have been widely used for biological monitoring of environmental quality. As some lichen species are virtually cosmopolitan organisms, they may be used for a survey of organic, inorganic, or radioactive contaminants on more or less a global scale, as well as for regional comparisons, and certainly at a more local scale. Some examples will be given for th...

The lichen specimens belonging to the order Lecanorales were collected from calcareous rocks in various areas of Mashhad. (Khorasan province). Specimens were taken back to the laboratory and identified. The identification of the species is based on morphology, anatomy and chemistry. They compose of  8  taxa  belonging  to 7 genera, namely, Lecanora conferta, L. muralis, Rhizocarpon umbilicatum,...
