Cladonia corniculata is distinguished from the morphologically similar C. weymouthii by the ecorticate base of the podetia and the Pd+ red reaction. Sometimes parasitised by Diploschistes muscorum ssp. bartlettii (Archer 1992b: 120). Earlier collections of C. corniculata from New Zealand were labelled as C. subulata and subsequently changed. However, these should be rechecked because both species occur in New Zealand. C. corniculata is distinct from C. subulata by (1) the presence of moderate branching, usually ½ to 2/3 of the way up the length of the podetium; (2) blunt tips; (3) the absence of cups. C. subulata does not branch, and has blunt or acute tips upon proliferations that often (but not always) arise from cup margins.
