Pseudocyphellaria argyracea is a species of foliose lichen in the family Peltigeraceae.

[2] Edvard Vainio transferred it to the genus Pseudocyphellaria in 1898.

Pseudocyphellaria argyracea has a foliose thallus that ranges from rosette-forming to irregularly spreading.

Its upper surface features laminal white soralia and pseudocyphellae, while the pseudocyphellae and lobe margins bear simple to coralloid isidia.

[3] From East Africa to India, Japan, New Zealand, South America, and the Pacific islands, Pseudocyphellaria argyracea has a broad distribution in the Palaeotropics.
