Cladonia aueri is characterised by: the lower third of podetia in mature specimens being bluish or blackened. C. aueri may be confused with C. subsubulata, which has the same chemistry. The axils and branches of C. subsubulata tend to swell at maturity, and the base of the podetia is never bluish or blackened. Immature specimens may be difficult to distinguish. Stenroos (1995: 108) synonymised austral material of C. aueri and also C. subantarctica Filson & A.W.Archer from Macquarie I. (Filson & Archer 1986: 230) under C. subsubulata, but I prefer to keep C. aueri separate.
