Aderkomyces thailandicus is a species of corticolous (bark-dwelling), crustose lichen in the family Gomphillaceae.

Aderkomyces thailandicus was first formally described by lichenologists Khwanruan Butsatorn Papong, Kansri Boonpragob, and Robert Lücking as a new species in 2011.

The type specimen was collected by the first author in February 2006 at Huai Nam Dung National Park in Chiang Mai Province, Thailand.

The lichen also features white, long sterile setae, which are hair-like structures, measuring 2–2.5 mm in length.

[2] The excipulum, a tissue surrounding the hymenium, comprises radiating hyphae embedded in a gelatinous matrix and is colourless.
