Fuscopannaria dissecta is a species of corticolous (bark-dwelling), squamulose lichen in the family Pannariaceae.

[1] Found in Japan, it was formally described as a new species in 2000 by Norwegian lichenologist Per Magnus Jørgensen.

The type specimen was collected by Syo Kurokawa from Mount Kōya (Wakayama Prefecture, Honshu) at an altitude of 800 m (2,600 ft); there it was found growing on the rotting bark of trees.

The lichen has a pale brown thallus that forms irregular patches comprising squamules that about are about 2 mm wide.

The squamules are dissected–cut deeply into fine lobes–and it is this character that is referenced in the species epithet dissecta.
