Apothecia immersed, flat to concave, black, shiny, c. 0.1mm diam. Arising from the prothallus.
Ascospores c. 17 x 5-6 Ám, curved, 8/ascus.
Thecium 100-110Ám.
Epihymenium aeruginose
Hypothecium hyaline.
Paraphyses branched and anastomosing, not or barely swollen at apices, lax in K.

Notes: South American material (Isla Desolacion) has an aeruginose epihymenium and hyaline hypothecium and the thallus contains atranorin in addition to norstictic acid, but is otherwise identical. This disjunct distribution (NZ Shelf Islands/Isla Desolacion) is shared by several other saxicolous species.
