A Comparison of Isolichenin and Lichenin from Iceland Moss (Cetraria islandica), N. B. Chanda, E. L. Hirst, and D. J. Manners,/. Chem. Soc., 1951 (1957). 

Percival also applied himself to the study of the polysaccharides from lichens, as, for example, the complex product of alkaline extraction of Iceland moss (Cetraria islandica). As a result of this work, he concluded that the polysaccharide consists of S-D-glucose residues united by various linkages 1,2, 1,3, 1,4, and 1,6, and includes also terminal D-galacto- and D-gluco-pyranose end groups. It was not possible to decide whether these linkages all occur in one polysaccharide. ...

ICELAND MOSS, Lichen islandicus consists of the dried thallus of Cetraria islandica (L.) Acharius sensu latiore, family Parmeliaceae. Characteristic constituents include bitter-tasting lichen acids usnic acid gives the bitter-taste and has antibacterial effects. It also contains polysaccharides, which form a mucilage Lichenin, a linear cellulose-like polymer of D-glucose, is soluble in hot water, and on cooling it forms a gel. The other polysaccharide is isolichenin, a linear starch-like polymer of D-glucose, soluble in cold water.

As the K efflux from plant tissue demonstrates membrane disintegration in particular, Nifontova et al. (1995) investigated the permeability of lichen membranes as a result of gamma radiation. Thalli of different lichen species were irradiated for this purpose. The membrane permeability in irradiated thalli of Cladonia arbuscula, Cetraria islandica and Hypogymnia physodes increased considerably in comparison with untreated control thalli. The K efflux from H. physodes thalli intensified with an increase of the radiation dose whereas no correlation was obtained for the K efflux and the radiation dose in C. arbuscula and C. islandica. The N content in Peltigera aphtosa appeared, however, to remain stable under acute gamma radiation.
