Is. RAUD is commemorated by DILLENIUS as having first 

 found this fine lichen in England. It is a subcircular 

 deeply lobed coriaceous leaf, oiten as large as a man's hand, 

 fixed near the centre, but free and somewhat raised at the 

 edges. When moist, as WAHLENBERG remarks, it is of a 

 remarkable leaden colour, but becomes paler when dried. 

 The upper surface is studded more or less with farina- 

 ceous tubercles, which often run into waved or circular 

 lines ; and the under one is curiously spotted with bare 

 white elevations. The shields are very rarely found. 



2. .V. pulmonaria, broad, irregularly and deeply lobed, greenish- 

 grey, deeply pitted, reticulated, more or less roughened with fa- 

 rinaceous lines, beneath pubescent, tawny, spotted. HOOK. Scot.
