Identification help! Manjano? Or mushroom?

[reef2.0]

Hi all

wondering if anyone could help identify what this is. It is all over the same rock, and each circle of it varies in size but is spreading very rapidly! trying to figure out if it is invasive and or predatory. thanks in advance

I don't think this is a majano... Others with more experience may be able to identify the shroom. Which I believe it to be. Best of luck
