Gray bubbles that pop

I'm in the middle of repotting my phal. There are a bunch of little gray bubbles that are just kinda laying in the potting mix. I picked one up and popped it between my fingernails. That was really gross. A lot of gray ooze stuff came out. I'm really curious what this is. I hope it isn't mold. I'm pretty allergic to mold. Thank you for any help!

Sounds like slime mold to me.

Does it look like this:

I found a better picture

That is the nasty stuff that is in my orchid. By chance do you know how to get rid of it?
It is strange that it is mold since my orchid sits right near an air vent and has regular air circulation.

That stuff in the second picture was in my new phal that I just bought the other week, too! If that's mold, maybe its a good thing that my cat knocked it over and forced me to repot it - even if it was in bloom. I thought maybe it was some kind of fertilizer...

Too much water and media that is deteriorating cause this. Unpot the plant, soak it in something like Physan, and repot using fresh media. Try keeping the plant a little on the dry side for a while.

Oh, you said you were repotting, so you may have already solved most of the problems.

I decided to repot because the blooms just died. I was originally going to leave the spike but it has started to turn brown. Now I need to figure out where I should cut it off at.
I'm glad that I started to repot, it definatly needed it. I only waited so long because it was in bloom.

I would cut the spike entirely off and let the plant rest.

That is the weirdest looking mold I've ever seen. I hope it will be ok that I didn't soak the plant before changing the media. I also hope it won't come back since I did a course bark/charcoal/perlite mix at the bottom with sphag moss on the top!

By off entirely do you mean down close to the leaves? Above the first node?
