Micrasterias americana Ehrenberg ex Ralfs 1848

West & West (1905, p. 117, pl. 53: 4-5 & pl. 54: 1-3) give a widespread distribution in Britain with several sites mentioned in Scotland but none for the Inner or Outer Hebrides. Recent sampling of slightly acidic oligotrophic water-bodies suggest it is rather scarce if not rare.
