Frogspawn that is not branching is called?

I recently started up another tank and got a new frogspawn today. I've always had branching frogspawn, but this new one doesn't have individual heads. All the heads are in a row.

It's like this

What is this called?

I believe it's 'wall' frogspawn, as ditto bubble et al.

I have a branching frogspawn but a wall hammer. Its a pretty cool combination.
