Punctum blandianum is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Punctidae, the dot snails.
The shell of P. blandianum is between 1.1 and 1.3 mm wide. The outer shell surface has a sculpture of radial striae, which are obvious under magnification. The umbilicus is about one third the width of the shell.[1]
This species is found in the United States, in the states of Tennessee, Virginia and Alabama.[2]
Population sizes of Punctum blandianum have been observed to be five times larger on highly acidic sites than on basic sites.[3]
