I thought I’d share a few photos of slime molds that have appeared over time in my bioactive terrariums.
None of them were introduced intentionally. They most likely hitchhiked in with forest humus, pine bark, moss, leaf litter, or live plants.
The photos show different observations from different enclosures and at different points in time. What fascinates me most is how some of them form large network-like structures across glass, wood, moss, and plants before eventually disappearing again.
I never expected to encounter so many interesting slime mold observations in my setups. Has anyone else with bioactive terrariums experienced something similar?

Hi everyone,
I found this very unusual organism growing inside two cork bark hides in one of my bioactive terrariums.
At first I thought it was some kind of egg mass because it looks like thousands of tiny pearls embedded in a white layer.
It is growing on cork bark under very humid conditions and has now colonized two different cork hides.
The enclosure contains:
Bioactive substrate
Cork bark
Decaying wood
Moss
Several slime molds
I couldn’t find anything similar and I’m not even sure whether this is a slime mold, a true fungus, or something else entirely.
Does anyone recognize this structure?
