This lichen occurs in coastal forests in Thailand, Vietnam, and northeastern Australia, where it grows on tree bark.

[1] Kalbionora was circumscribed in 2017 by Mattika Sodamuk, Steven Leavitt, and H. Thorsten Lumbsch to contain a new lichen discovered by Sodamuk in a mangrove forest in eastern Thailand, where it was growing on the bark of Ceriops tagal.

The specific epithet refers to the occurrence of the lichen in the paleotropics, while the generic name honours German lichenologist Klaus Kalb.

[1] Its standing as a genus has been accepted in recent large-scale updates of fungal classification.

The spores are hyaline, thin walled, and ellipsoid, measuring 8.9–10.4–11.8 by 3.2–3.8–4.4 μm.
