Myeloconis parva is a species of corticolous (bark-dwelling), crustose lichen in the family Porinaceae.

[1] Found in Amazonian Brazil, it was formally described as a new species in 1996 by Patrick M. McCarthy and John Elix.

The thallus is continuous, with a matte to slightly glossy surface that is closely appressed or somewhat raised near the margin.

Closer to the centre, the thallus is raised, peeling and flaking, and very uneven, and is approximately 30–100 μm thick.

The ascomata are irregularly convex thalline swellings, each with a shallow, 70–100 μm diameter, apical depression and a minute, medium to dark brown ostiole.
