Gold dust lichen - I only know of the species I've suggested but realise there are others in the genus. On red stringybark, low to the ground. None observed on other nearby trees.
Hi Karen I don't feel confident of confirming this as Chrysothrix candelaris. My reference shows that it doesn't occur in Australia: https://en.wikipedia.org/wiki/Chrysothrix_candelaris How about Chrysothrix sp. (genus)?
Thanks Michael (for looking at this and my other uploads!). I'm more than happy to stick to the genus. I doubt my images have sufficient detail to make a call to species anyway.
ALA records support that particular species being in Australia: https://bie.ala.org.au/species/NZOR-6-77455 As does ABRS: https://www.anbg.gov.au/abrs/lichenlist/VOLUME%2057/Chrysothrix_candelaris_d.html
