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. 

Eight of 100 lichen species contained phytagglutinins Peltigera aphtosa agglutinated human red cells in titer 1 400 as saline extract (Estola and Vartia, 1955).
