[3] Teuvoahtiana has members that are crustose, areolate, and squamulose–an unusually diverse range of forms for a single monophyletic branch of the Teloschistaceae.

In some cases, the peripheral zone of the thallus has unique areoles that are elongated to form distinct lobes.

[3] The apothecia of Teuvoahtiana vary from medium to large size, often congregating in dense clusters.

They have a lecanorine to zeorine structure, with a flat disc that displays a spectrum of colours from soft yellow to a more vibrant pinkish orange-brown.

The true exciple, or outer layer, is characterised by a complex interwoven structure, known as "textura intricata".
