Here's a few labeled picture. Your red yuma appears to be a king kong yuma not a godzilla. They are multi colord as youth and grow to be mostly red with a green skirt.
I would also agree that this is a king kong yuma and not a godzilla. My godzilla yuma offsprings show the green skirt on the base (not only on the bubbles) which yours is lacking. This is one of the most noticeable details that separate the 2 mushrooms.
Firstly godzilla yumas have pink not red (generally speaking). Secondly king kong yuma babys are multicolor but turn red as they grow (green, red, yellow mouth). The smaller the king kong yuma the more colorful. Baby godzilla shroom look about the same there entire life colorwise.
Definitely not a Godzilla bud, the green is in the actual vesicle/bubbles as well. And is ridiculously apparent as babies. Here’s some pics of my Godzilla momma so you can compare and her babies.
Here's a picture of my godzilla yummas. You can see how clear the green base is on my mushrooms, even the small ones. Yours only has the green around the bubbles
