Pseudocyphellaria neglecta is characterised by: linear-laciniate to broadly rounded lobes with entire to crenate-incised, often densely phyllidiate margins; a wrinkled to faveolate upper surface, occasionally with phyllidia regenerating from margins of cracks, but without soredia; a white medulla; a cyanobacterial photobiont; a pale-buff to brown or blackened lower surface, with scattered yellow pseudocyphellae; and a complex chemistry of depsidones, hopane-triol, depsides and pigments.
