Change link style for specific item (Oulipo theme modded)

Hey there,

On my blog https://astroaficionado.net, I have the following set-up for links (using the Oulipo theme that I’ve modded to my liking)

.entry a, .navigation a {
	color: #000;
text-decoration: underline;

}

a:hover {
background-color: #4f4f4f;
}

I also have the Daring Fireball linked list plugin set up, adds a glyph at the end of my “linked list” posts (as seen on the first post on the blog with the diamond)

My problem is, I don’t want this glyph to have the same style as the general links on my bog. More precisely, I don’t want the black hover background, the underline, and I want the hover-over colour to be blue (don’t have a specific hex code off the top of my head).

Here is the part of index.php containing the permalink glyph code:

Any help is very appreciated. Hope I was clear enough.
