Description : Flora (1985: 343).
Chemistry : Cortex K+ yellow; medulla K+ yellow→red or K−, C−, Pd+ orange; containing atranorin, chloroatranorin, salazinic acid (major), consalazinic acid (minor) with or without unidentified compound #27 (Hale 1987).
N: Northland (Waipoua Forest) to Wellington. S: Nelson (Lake Rotoiti) to Southland (Manapouri). St: Widespread as an epiphyte of Nothofagus (on trunks and also on canopy twigs) Known also from Tasmania (Galloway & Elix 1983; Hale 1987; Elix 1994m; Kantvilas & Jarman 1999; McCarthy 2003c, 2006).

Parmelia testacea is characterised by: the corticolous habit; the adnate, sublinear to mostly subirregular lobes; marginal pseudocyphellae; the absence of soredia and isidia; the sparse to moderately dense rhizines that do not project beyond the lobe margins; small ascospores 11–15 × 7–10 μm; and the presence of salazinic acid with or without the presence of unidentified compound #27. Externally it is indistinguishable from P. subtestacea, which has echinocarpic acid rather than salazinic acid as the major medullary compound.
