Columella aspera

This tiny snail is only 2mm high and 1.3mm across. It is very similar to C. edentula but relatively more squat and tapering. The brown shell is more or less opaque with faint, irregular growth ridges giving it a rough surface. The mouth is nearly round and without any teeth in the aperture.

Columella edentula is slightly taller, often with an extra whorl, and has smoother, fainter and more regular striations on the shell.

Coniferous and deciduous woodland, poor acid grassland and typically in dryer and less calcareous habitats that C. edentula.

All year round.

Widespread but uncommon in Britain.

Rare or under-recorded.
