Ramalina erumpens

Ramalina erumpens is yellow-green in colour, and has erect flat branches typically measuring between in length, with a width of between . The species had forked apices and marginal soralia , which are rimmed, round to ellipsoid, and produce fibrils. == Taxonomy ==

The species was first described in 1996 by Dan Blanchon, John E. Braggins and Alison Stewart, noticing morphological differences in South Island specimens labelled as Ramalina pacifica. The species epithet erumpens is Latin for "breaking through". Two subspecies are known, Ramalina erumpens var. erumpens and Ramalina erumpens var. norstictica. The latter was identified as a subset type specimens of the lichen tested positive for norstictic acid and salazinic acid. == Distribution and habitat ==

The species is found in the South Island of New Zealand, between Banks Peninsula and western Southland, typically in native forest remnants in coastal areas up to above sea level. Var. norstictica is found on the Otago Peninsula, where var. erumpens can also be found. == Ecology ==

The species is corticolous, found primarily on the bark of Dacrycarpus dacrydioides, but can also be found on other trees and shrubs. ==See also==
