224 LICHENS. 



It is a handsome species, growing in extensive patches ; 

 and we were grateful to the wild woodland above Brack - 

 lvn Bridge for furnishing us so great a treasure. Tourists 

 launch into well-deserved praises of that brawling stream 

 with its magnificent rocks, and dashing waterfalls, and 

 bending trees ; but to us there was an added beauty, an 

 extra claim on admiration, in the abundant lichens 

 thrown together in wild profusion, hanging, as silver foli- 

 age, from the aged branches, and lapping one over another 

 like tiling among the tall mosses. There, where ever- 

 lasting moisture hangs, the mosses and lichens grow to 

 double their usual size ; the rocks* are studded with crus- 

 taceous lichens — Lecidia, Lecanora, and Urceolaria — and 

 draped with pendant masses of interwoven feather moss 

 and oak lungs, fork moss and dog lichen, while hundreds 

 of Yellow chanterelles, Fly agaries, and pink Bussulae 

 spread their domes over the verdant tapestry.
