Pseudocyphellaria fimbriata is characterised by: linear-elongate, complexly dissected lobes with markedly phyllidiate margins; phyllidia with glistening white marginal hairs; a coriaceous, minutely scabrid-areolate upper surface; a white medulla; a green photobiont; a pale red-brown to dark-brown velvety tomentose lower surface with numerous, prominent white pseudocyphellae; and a two-hopane chemistry. It may be parasitised by the lichenicolous fungus * Arthonia santessoniana (q.v.).
