'''''Pseudosagedia aenea''''' is a widespread species of [[corticolous lichen|corticolous]] (bark-dwelling) [[crustose lichen]] in the family [[Porinaceae]].<ref name="CoL"/>
==Taxonomy==
''Pseudosagedia aenea'' was first [[species description|described]] as ''Verrucaria aenea'' by [[Gustav Wilhelm Körber]] in 1855. It has been shuffled to several different genera in its taxonomic history, including ''[[Porina]]'', ''[[Pyrenula]]'', ''[[Sagedia]]'', and ''[[Trichothelium]]''.<ref name="Species Fungorum synonymy"/> In 1995, the lichenologists [[Josef Hafellner]] and [[Klaus Kalb]] transferred it to the genus ''[[Pseudosagedia]]'', establishing its current name ''Pseudosagedia aenea''. The [[botanical name|species epithet]] ''aenea'' comes from [[Latin]] and refers to the bronze-like appearance of the lichen.<ref name="Hafellner & Kalb 1995"/>
The genus ''Pseudosagedia'' is characterised by dark purplish pigments (called ''Pseudosagedia''-violet) in the inner wall of its fruiting bodies. This pigmentation pattern helps distinguish it from related genera in the family.<ref name="Hafellner & Kalb 1995"/>
