Reichlingia zwackhii is a species of corticolous (bark-dwelling) lichen in the family Arthoniaceae.

It was first formally described by German lichenologist Johann Heinrich Sandstede in 1903, as a member of genus Arthonia.

Andreas Frisch and Göran Thor transferred it to the genus Reichlingia in 2013.

[2] Peter Wilfred James proposed the variety Arthonia zwackhii var.

macrospora in 1978, on the basis of specimens collected from Britain that had consistently larger ascospores and different lichen products.
