[1] Found in Southeast Thailand, it is characterised by its sorediate features and its distinct ascomata and ascospores.

The type specimen was discovered by the first author in Trat province, Thailand, in Ban Pak Khlong Nam Chiew mangrove on a large trunk.

The inner part of the soralia is white, containing abundant hyaline crystals that do not dissolve in a potassium hydroxide solution.

It also differs from non-sorediate species like E. diederichiana and E. tropica in terms of thallus structure and ascospore features.

Its distribution and habitat preferences may be influenced by the presence of suitable substrates and specific environmental conditions.
