Fungus on my 9 month old beardie

[Sebastian27]

Last night, I noticed some crusty discolored patches on my beardie's underside. I took him into the pet store this morning and the person there said it looked like fungus and recommended an exotic vet however, there are no times available until Friday morning which is 3 days away. I researched a little and found that it looks like yellow fungus.

I'm wondering, should I wait until then to take him in or should I take him somewhere sooner?
