Common on wooden buildings within mini putt golf course. Associated with Xanthoparmelia sp., and Syntrichia antarctica. Thallus upper surface greyish-white (when wet or dry - here shown wet), finely covered in reticulate cracks, sorediate, soredia in marginal laciniae; thallus underside with broad pale brown margin devoid of hairs, otherwise densely covered in black hairs. Apothecia present. Spot tests - cortex K+ red, Medulla K+ red. This is probably the most common Parmotrema in New Zealand, though the name as used here may be incorrect. Furthermore what is called P. reticulatum in New Zealand is highly variable and may constitute several entities.
