Soralia roundish, concave, 0.5–1.2 mm diam., remaining distinct or coalescing, with granular soredia, yellowish green to yellowish gray. Apothecia sessile, strictly constricted at base, 0.6–2.0 mm diam., lecanorine; disc red-brown, shiny, plane, epruinose; margin concolourous with thallus, prominent, thick, smooth, entire to verruculose, flexuose.

The new species is named after the area East Africa where it has been collected.
This new species is currently only known from the type locality in the Rift Valley province of Kenya, where it was found growing on bark in a degraded montane forest dominated by
