I had an all-Fuggles IPA the other day and thought of you Denny. It was certainly earthy but not at all bad. Didn't get a lot of citrus either.
I use a whole lot of Fuggles and "earthy" is exactly how I would describe it. "Dirt" sounds so negative.
Willamette is a pretty good substitute, so there shouldn't be any clash. Never used Galena that I know of so I can't comment there.
I recently brewed a "legacy" batch of my Noti Brown Ale recipe. It uses a lot of Willamettes and over the years I'd switched them out for other hops. It was the first recipe I ever won with, so I thought I'd revisit it in the original form. I could immedialtely taste the earthy, dirt, whatever you want to call it. I gave some to 2 friends, both BJCP, and that was the first thing they commented on.
Stay away from X-462 then, had it recently at a well known brewpub that makes a beer called Hop 2 It. Both of us got earthy, herbal. Finish was a surprise, chocolate like. The beer was pale, so no dark malts.
This might make a white stout.!
