Splanchnonema lichenisatum is a species of corticolous (bark-dwelling) lichen in the family Pleomassariaceae.

The type specimen was collected by the first author from Mount Juwang (North Gyeongsang Province) at an altitude of about 350 m (1,150 ft); there, it was found growing on the bark of an ash tree.

[1] The lichen has a thin, pinkish-brown thallus that is immersed in the bark, and covers areas of up to about 5 cm (2 in) in diameter.

Reactions to common chemical spot tests are negative, and no lichen products were detected using thin-layer chromatography.

Two of the most unique characteristics of the species are the presence of kidney-shaped (reniform), compound ascomata, and the lichenisation–which is quite rare in the genus Splanchnonema.
