Shell description
The shell is very small, ovate, obtuse, indistinctly, spaced striate, glossy purplish brown. The shell has 4½ whorls, that are rather convex, high, rapidly increasing, joined by a somewhat impressed suture, the penult large, almost ventricose. Umbilical opening is moderate.
The aperture is semirotund, nearly quadratic, without any folds. Peristome is scarcely expanded, thickened liplike, bordered with bluish black, the margins are connected by a very weak callus, the right margin is arched at the insertion.
The width of the adult shell is 1.03–1.20 mm, the height is 1.63–2.00 mm.[http://www.staff.amu.edu.pl/~polmal/smp/v97.htm Vertigo (Vertigo) genesii (GREDLER, 1856)] {{webarchive |url=https://web.archive.org/web/20050105051600/http://www.staff.amu.edu.pl/~polmal/smp/v97.htm |date=January 5, 2005 }}.
