Any closer shots you can add? Might be Hericium.

After seeing pictures of Hericum, I do think that is the correct id.

I took some more shots. I don't know whether I should merge those photos into this observation. It is the same fungus, but the photos are a week apart.

Thanks, Ken-Ichi!

This fungus is on a majestic oak tree at Gunn High School. Will this fungus compromise the health of this tree?

You should probably consult an arborist or a forester. From what I can glean for a cursory search, I think if it's fruiting then there might already be significant rot. Not sure if the fungus causes the rot or just grows in compromised wood. Here are some links:
