Help possible slime mold identification!

[Gala Montiel]

Hello everyone!

I went to the forest the other day and tried to forage some slime.

I found this on decaying wood, grabbed them, and took them home to some Petri plates with coffee filters (I'm aiming to grow them in agar), I'm not sure if what I have here is P. polycephalum (giving the intense yellow color). Could someone help me know if I'm on the right track???

It lacks organization, and is quite transparent with stuff floating in it, I doubt that it's a slime mold.
