^^^ +1 that's always a huge help with the fuzzier sticks.I'd also say blast it with a Turkey baster to make the PE retract to expose the coralite shape
Closer look it almost has tube like coralites like a granulosa. Not raspier corlaites like the tenius or aculeus
A. aculeus has slightly immersed nariform radials, that flare a tad, they are not rasp like like tenuis. I do see what you are saying though, however the tubular corallites I am seeing look like axials / Incipient axials.
Need another pic, like you said polyps retracted helps a ton!
