I'm panicking. Help! Mold?

[jkt97401]

I recently bought a clearance orchid from Fred Meyer because it looked healthy and there was a spike forming! This is a Sharry Baby or it was labeled as such. I was alarmed this morning to see this growth of what appears to be mold on this and a few of my phals. I haven't faced this issue yet, can someone help me? Also, my phals are in S/H if that matters.

The temperature in the room doesn't get lower than 65. It usually sits between 70 and 75 with a RH of about 60-65% abd there is a fan blowing for circulation
