Parmotrema reticulatum
≡Parmelia reticulata Taylor in J.T. Mackay, Fl. hibern. 2: 148 (1836).
≡Rimelia reticulata (Taylor) Hale & Fletcher, Bryologist 93 (1): 28 (1990).
Description : Flora (1985: 361).
Chemistry : Cortex K+ yellow; medulla K+ yellow→red, C−, KC+ red, Pd+ orange; containing atranorin, chloroatranorin, salazinic acid (major) and consalazinic acid (minor).
N: Northland (Three Kings Is) to Wellington. S: Nelson to Southland. St: A: C: Very widely distributed on rock and wood in both coastal and inland habitats. A common and early coloniser of decorticated wood (fence posts, gates, farm railings), shade cloth, exotic trees (especially fruit trees) in parks and gardens; more commonly found in disturbed habitats than on native vegetation. A very widely distributed species worldwide, pantemperate, pansubtropical, and one of the most common foliose lichens in the world (Hale & Fletcher 1990; Moon et al. 2001; Aptroot 2002e; Nash & Elix 2002h; Louwhoff & Elix 2002b; Wolseley et al. 2002; Kurokawa 2003; McCarthy 2003c, 2006).

Illustrations : Dobson (2000: 272 – as Parmelia reticulata; 2005: 311); Brodo et al. (2001: 643, pl. 785); Kantvilas et al. (2002: 155– as Rimelia reticulata).
Parmotrema reticulatum is characterised by: the corticolous/lignicolous/saxicolous habit; the ciliate lobe margins, laciniae with marginal to submarginal soredia; and the presence of atranorin, chloroatranorin, salazinic acid (major) and consalazinic acid (minor). Recent molecular studies on the P. reticulatum complex clarify the taxonomy of this group (Divakar et al. 2005a).
