Agonimia octospora is a species of corticolous, (bark-dwelling) squamulose (scaly) lichen in the family Verrucariaceae. It was formally described as a new species in 1978 by the lichenologists Brian John Coppins and Peter Wilfred James. The type specimen was collected in Glengarriff Forest in (West Cork (Ireland), where it was found growing on the bark of oak. Characteristics of the lichen include its colourless ascospores that number eight per ascus, and its tiny squamules (up to 0.3 mm long) that are closely attached (appressed) to its substrate. Its spores typically measure 60–75 by 20–26 μm. The lichen is found in Europe and South America.
