The type specimen was collected by the first author in Zona de Amortiguación, Mundo Nuevo, La Calera, Cundinamarca (Colombia) at elevations ranging from 2,900 to 3,100 m (9,500 to 10,200 ft).

[2] The lower surface of Lobariella reticulata is cream-coloured to pale yellowish brown, featuring a very short, dense tomentum made up of hyphae composed of spherical cells.

The lower cortex mirrors the upper in structure, being paraplectenchymatous and 10–15 μm thick, formed of 2–3 cell layers.

[2] Apothecia (fruiting bodies) in Lobariella reticulata are abundant, cup-shaped, and can reach up to 7 mm in diameter, featuring thick, strongly prominent, crisp, pale grey margins.

Ascospores of Lobariella reticulata are narrowly fusiform, measuring 60–80 by 4–5 μm, with 7 septa and a hyaline appearance.
