Malmidea allopapillosa is a species of corticolous (bark-dwelling), crustose lichen in the family Malmideaceae.

The type specimen was collected by the author in 1980 from a cloud forest in the surroundings of Tovar, Páramo de Mariño, (Mérida) at an altitude of 3,000 m (9,800 ft).

[1] Malmidea allopapillosa is a crustose lichen with a thallus that is either continuous or cracked and measures 50–100 μm in thickness.

The margin of the apothecia is thin, approximately 0.05 mm thick, and varies in colour from whitish-grey to dark brownish-grey.

[1] Chemically, this species is characterised by the presence of atranorin as a major component, along with approximately 10 unidentified xantholepinone substances, detectable using thin-layer chromatography.
