The photos show it dry and curled up. With moisture it opens, as shown here (http://www.cpbr.gov.au/lichen/photos-captions/xanthoparmelia-semiviridis-f-251.html). It is very rarely seen with the circular, spore-bearing apothecia (http://www.cpbr.gov.au/lichen/photos-captions/xanthoparmelia-semiviridis-apothecia.html). So, Michael, you'll have to go back and check every one of these for apothecia!
