Lobaria scrobiculata (Scop.) DC.


Thallus lobes large, upper surfaces deep blue-grey when wet, drying yellowish grey-buff, weakly and sometimes scarcely ridged, with rounded, blue-grey soralia, underside with a reticulate pattern of pale brown tomentum, differs from other British Lobaria species in having a cyanobacterial main photobiont. On deciduous tree bark, rarely mossy rocks, coastal and in old forest, restricted to unpolluted areas in the north and west, formerly more widespread.
