I might actually have few things you're looking for. I have iridescent dictyota that glows blue with high light, I recently got what I believe is Cryptonemia crenulata , and I may have a neomeris species but I'm not entirely sure.
Here is some pictures. Unfortunately, I don't have a pic of the cryptonemia on my phone right now but I could send you one later. This little batch of dictyota is lower in the tank so you can't see the blue iridescence. When I bought this green algae it was labeled as "Green Neo finger algae" on ebay. I'm nearly certain it is not Neomeris annulata but it may be a different Neomeris species. It didn't do great when I first added it to my tank so I lost half of it but, it is bouncing back now.
