Hypogymnia hultenii is a species of foliose (leafy) lichen in the family Parmeliaceae.

[3] Hypogymnia hultenii is found exclusively in cool coastal coniferous forests, due to it mainly growing on the small twigs of such trees.

[4] The origin of the disjunct populations of Hypogymnia hultenii is still being researched.

It is likely that it is due to its once undisturbed range during the Pliocene being fragmented by glaciers.

This is supported by its incredibly slow rate of genetic drift, which has prevented speciation between all of these ranges.
