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.
Are those apothecia on the edges of the strands or just plump soralia ?

a very unusual lichen on rock. Bluish black upper surface with shiny tips of lobes and a lighter bluish/gray ring near edge. Lots of isidia (?) covering the center of the lichen. Tight against rock - couldn't get a good lower surface picture, as it just crumbled.
crappy picture - have to figure out how to photograph these dark lichens on sunny days.
broad lobes, lots of isidia, translucent cortex (?), didn't see "thickly white tomentous" lower surface
- not sure of ID.... checking into alternatives. Vs. Collema furfuraceum
abundant in a patch of coyote bush
