Wow! When did that go on-line? Amazing work! Looks like full coverage of plants, ferns, liverworts, and lichens.

The description of vitellina as composed of convex to spherical granules seems to match these observations perfectly. I continue to vote for vitellina.

Both species are cosmopolitan, so let’s check in with our (antipodal) neighbors. In his “Flora of New Zealand Lichens” (2007, vol. 1, pp.266-273), D. J. Galloway concludes the discussion of each species with a short characterization (click on the name to go to the page):

Candelariella aurella “is characterised by: the scanty to non-apparent thallus; abundant, bright-yellow, K− apothecia; and 8-spored asci. It is distinguished from C. vitellina by its dispersed apothecia that are never crowded, by the lack of a defined thallus, and by the size and number of the ascospores.”

Candelariella vitellina “is very variable but is characterised by: scattered to contiguous, convex to spherical granules, or compacted into small, shortly lobulate clusters of often fertile, subsquamulose rosettes; the colour ranging from yellow to dull, deep-orange or brown-yellow; the numerous, congested apothecia; and multi-spored asci.”

His key to Candelariella of New Zealand lays out the differences.

The Flora of Australia includes a key to Candelariella of Australia, together with two photos (click on the name to go to the page):

Candelariella aurella (the ID is tagged with a “?”)

Yep, still looking at Candelariella vitellina and C. aurella.

Just need to decide how much thallus C. aurella is “allowed” to have.

Candelariella?
