Scuba guy, I thought yours was tentatively identified as as a piece of Pseudopterogorgia. Sorry about that. From Borneman's book, Muricea contains less than 20 species, all described as having "rough calyces" and appearing "even with extended polyps" "very spiny." I can't say mine looks spiny. They are also described as being "mostly grayish white, orange-brown, or brown."
Perhaps the gorgs here are Plexaura sp.? They are described as "bushy" with "thick branches," comparatively dry and rough, with small, minimally raised, pore like calyces and retractile polyps. Most are "shades of purple, brown, and purplish gray."
The reason why I asked about the slit pore is because I have often wondered about Plexaurella sp. They are described as having "elliptical apertures from which a dense number of large, fuzzy, retractile polyps emerge." "They are often tall and bushy, with thick, sparse, cylindrical branches." Their color is often yellow to brown or purple-gray.
Here is a photo of one of my gorgs.
And here is a close up of one of the branches:
This is also mine, a different gorgonian, but I think it is the same species:
