Though it is found across tropical and subtropical regions of the New World on various substrates, its distribution might be wider than currently known due to collection biases against sterile, asexually reproducing crustose lichens.

The species epithet, blochiana, is a tribute to Ellen D. Bloch, the collections manager at the cryptogamic herbarium of the New York Botanical Garden.

[2] Ramboldia blochiana features a superficial thallus that ranges in color from creamy white to dark gray and can be thin and continuous or thicker with irregular areoles.

It is dispersed across the tropical and subtropical regions of the New World, with known collections in Brazil, Venezuela, the Dominican Republic, Haiti, southeastern Coastal Plain and southern Appalachian Mountains in the US, and Mexico.

The authors suggest that the actual distribution of Ramboldia blochiana may be broader, as sterile asexually reproducing crustose lichens often face collection bias and thus there is often insufficient data to determine their full range.
