Pseudopyrenula miniflavida is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae.

Found in Brazil, it was formally described as a new species in 2019 by lichenologists André Aptroot and A.D.Nunes.

The type specimen was collected from Mata do IFS (Quissamã, Sergipe) at an altitude of 50 m (160 ft).

The hamathecium (i.e., all of the fungal hyphae or other tissues between asci) contains yellow oil droplets that dissolve but do not change colour in a solution of KOH.

The specific epithet miniflavida alludes to both its small spores (the smallest in genus Pseudopyrenula) as well as the characteristic yellow oil droplets in the hamathecium.
