A major characteristic of the species is the coralloid (coral-shaped) clumps of isidia-like outgrowths on the thallus surface.

The thallus is characterised by verrucose formations that are more or less spherical and coalesce with age, forming coralloid clumps of thin, isidia-like outgrowths.

The species has soralia that are more or less punctiform, measuring around 0.01 mm in diameter and intense orange-yellow in colour, emerging from warts that break off at the tips.

The excipulum is of the granifera-type, entire, and ranges in colour from whitish and cream-coloured to greyish, typically paler than the disc.

The centrally located hypothecium is 75–85 μm high, narrowing towards the margin, and is dark brown in colour, not reacting to potassium hydroxide (K−).
