It is monotypic, containing the single foliose Himalayan species Emodomelanelia masonii.

It was named in honour of Mason Hale, the "preeminent student of the Parmeliaceae".

[2] Characteristics of the genus Emodomelanelia include an olive brown to brown thallus, narrow to moderately broad lobes, a non-pored epicortex, the presence of effigurate pseudocyphellae (i.e. with a lobed shape), and bifusiform conidia.

[2] Emodomelanelia masonii is endemic to the Himalayas, where it grows on rocks in alpine and subalpine habitats.
