Platygramme lueckingii is a species of script lichen in the family Graphidaceae.

The species epithet honours German lichenologist and colleague Robert Lücking, "for his many contributions to the knowledge of Graphidaceae".

[2] The lichen has a thin, yellowish-green to greenish thallus that is tightly attached to its bark substrate.

Its ascospores are oblong to ellipsoid in shape, muriform (with 8–9 by 1–3 internal locules) and dimensions of 35–45 by 110–155 μm.

Platygramme hainanensis is similar in morphology and appearance (also found on Hainan Island), but this lichen does not have two-spored asci.
