Filsoniana kiamae is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae.

These areoles are flat to somewhat convex and tightly adhered to the substrate, with their upper surface having a brownish-orange to greenish-brownish orange colour.

In larger rosettes, the blastidious mass is confined to the central part, with a peripheral zone of 1–2 mm typically lacking blastidia.

They are sessile, round, flat, and can be either lecanorine or zeorine in type, with brownish-orange thalline and proper margins, and a reddish to reddish-brown disc.

Paraphyses are slightly expanded towards their tips, reaching up to 7 μm in diameter, often containing oil droplets in the upper cells.

[3] Filsoniana kiamae is typically found in natural indentations and fissures of granite rock outcrops, as well as on sandy limestone surfaces.
