Architrypethelium submuriforme is a corticolous (bark dwelling), crustose lichen species within the family Trypetheliaceae.

The type specimen was collected in the rainforest of Catas Altas, Santuário do Caraça, Minas Gerais, Brazil, at an altitude of 1,200–1,400 m (3,900–4,600 ft).

[2] The thallus of Architrypethelium submuriforme is dull and pale ochraceous green, capable of covering areas up to 25 cm (10 in) in diameter.

Its surface is bullate (blistered), featuring ellipsoid patches intermixed with linear black areas.

The chemistry of the thallus shows no reaction to UV light or chemical tests, indicating an absence of secondary metabolites (lichen products).
