Common Coral Slime (Ceratiomyxa fruticulosa), taken July 25, 2024, in Georgia, US
The most common slime mold in my area! This particular colony lives in a rotting tree trunk and has a bloom of fruiting bodies if it rains hard enough, always in the same spot. I find slime molds fascinating—they're just so weird and unique! Under a macro lens like this, they look like something from an alien planet!
