Growing white clumps

[James Becwar]

Any idea what the white clumps are? They tend to grow under rocks and in my GSP.
Thank you for your help

Those are tunicates as well There are different variations. The white in the first picture could be sponges as well. But either way they're both harmless filter feeders
