Yellow discharge on my plants. (insect, leaves, animals, growth)

Hi:
I noticed a yellow discharge on some of my plants on Friday. This yellow discharge was as if some animal/insect had sprayed tiny yellow grains on the stem and leaves. Two days later, this yellow stuff is now hardened into white stuff. What exactly is this? Please see before-after pictures below.

On Friday:



Two days later:



Thanks,

I really don't know what that could be, possibly some kind of fungal growth.
However there is quite a lot.Have you tried shaking it off?
It apparently spreads to the other plants so should be removed asap.
Let me know if you found out what it was.

Thanks, Pat.

I did some additional research and I found out that the fungus is called Fuligo septica aka the dog vomit slime mold. It is harmless to humans, animals and plants. For details, see Tom Volk's Fungus of the Month.

Thanks,

Dog vomit slime? Nice. At least it is harmful.
