Neocatapyrenium disparatum is a species of squamulose lichen in the family Verrucariaceae.

Found in the United States, the lichen was described as a new species in 2005 by Othmar Breuss.

It is the only member of genus Neocatapyrenium that occurs outside of Eurasia.

The type specimen was collected by Clifford Wetmore in a rocky valley in Big Bend National Park, Texas, at an elevation of 6,300 ft (1,900 m); here the lichen was discovered growing on moss over soil.

The specific epithet disparatum, meaning "separated", alludes to its similarity with and separation from the lookalike species Neocatapyrenium cladonioideum.
