Here is a couple...

Any guesses at what these are? They are some of my favorites and I figure I should know what they are.

Lokani http://coral.aims.gov.au/speciesPages/species_metadata/0621/view#
Loisetteae http://coral.aims.gov.au/speciesPages/species_metadata/0837/view#
Cytherea http://coral.aims.gov.au/speciesPages/species_metadata/0020/view#

Would be my initial guesses.

I do agree with number one, number three looks right but it certainly hasn't tabled out real thin. Number two I don't think is a loisetteae, at least it doesn't look like any of the pics I have seen.

Yeah the second one was my quickie. Just going by the coralites and tips, not overall growth.

cali tort
last one doesnt strike a bell

I thought Cali tort has dark green base with blue tips. That acro has a green base with pink polyps and tips. Not looking for trade names since I got them "wild" anyways.
