P. mariensis P. minuscula P. pubescens Pseudephebe is a genus of fruticose lichens in the family Parmeliaceae.

Molecular phylogenetic work published in 2016 showed that the genus is monophyletic, and within the alectorioid clade of the family Parmeliaceae.

[3] Although Boluda and colleagues considered this to be synonymous with P. minuscula,[1] Fryday and colleagues "consider the distinct pseudocyphellae, detectable norstictic acid, thick cortex and the unique propagule system of the Falklands collections as sufficient to provisionally maintain it as a distinct species.

"[3] Pseudephebe lichens are small and fruticose, ranging in colour from brown to almost black.

Their thalli somewhat resembles coarse, tangled hair, although sometimes regions around the periphery of thallus have flattened branches that are almost foliose.
