20. Parmelia fulgens? (Ach.; Bab. l.c. p. 291). 
Has. On the ground: Cheshunt, Archer. Barren. 
Specimens very minute, growing over some other barren, glaucous Lichens, not a quarter of an inch in diameter, 
more deeply coloured than P. fulgens usually is, almost orange-coloured, thick, margins of the thallus paler; the 
centre almost ferruginous, and simulating the appearance of confluent immarginate apothecia. Very probably this 
is something different from P. fulgens, but being barren it cannot well be proposed as new. Several allied species 
are mentioned by Nylander (Enum. Gen. Lich.), to one of which it may possibly belong.
