A very rare plant in the British Islands ; many of the citations 
are based on the mistaken identity by Dillenius of a plant from St. 
Vincent’s Rocks, Bristol. According to Crombie (ll.c.), however, 
Dillenius certainly was dealing with this species, as the two specimens 
in his herbarium are typical, though both of them, of continental 
origin, were received from Celsius. The British specimen from St. 
Vincent’s Rocks (Lichen petraeus cinereus Anglicus Buddle Hort. 
Sicc. ii. fol. 36 in Hb. Sloane) has proved on examination to be Der- 
matocarpon miniatum. Crombie and others had evidently accepted 
Dillenius’ determination of the specimen without verification. 
Lichen deustus Huds. Fl. Angl. p. 455 (1762) (non Linn.), though 
quoted by Crombie as a synonym of the above, is also a misidenti- 
fication.
