I saw this growing in a show tank in LA and there's so many forms it takes that I think it's one of the coolest liverworts out there. I've seen it dark green in free flowing form, I've seen it look like a clump of brain matter and translucent, but I actually really like how they get undulated and clump together sometimes like how mine are doing. I just stuck a bunch into an opening in the driftwood and let it do it's thing. As a Landscaper, I like watching landscape mature over time and the less I have to do, the better.
