I don’t see any evidence that there are multiple species hiding under the names C. aeruginascens or C. aeruginosa.

A quick tree I just made: http://images.mushroomobserver.org/chloro.jpg

then there’s this:

which describes 13 new species and one new subspecies. New Zealand’s hyperdiversity notwithstanding, I think it’s safe to assume that the genus is much more complicated and much less binary (ie: aeruginascens vs. aeruginosa) than previously thought.

a confirmed C. aeruginascens… with a centrally-stipitate apothecium that whitens/lightens as it ages/dries. if the Wikipedia spore ranges of each spp. are to be trusted (they are uncited), there is overlap there as well. presence/absence of encrustation on ectal excipular hyphae appears to be the most diagnostic feature, but no observation on the site as of the time of writing (June 2016) shows them in a micrograph or drawing.
