Default Fuligo septica (slime mold)

...commonly known as "dog vomit" slime mold, among other colorful common names.

At first I was excited! Slime mold! I don't see if very often, and last time, I wasn't quick enough to collect some.

Turns out, it's not particularly exciting under the microscope. It's a colony or a collective organism, or something, and it's made of many tiny individuals.





Then something awesome happened. The slime mold body floated really well, probably because it's a big loose structure of what I'm calling spores. I don't know if this was before or after I put it in water, but the cells all clumped around tiny air bubbles:

Woa that's awesome!

Since slime molds aren't really molds, cell would be better than spore. Spores are closer to seeds which grow a cellular network outwards from the starting spore cell.

Slime moulds are cool

When a slime mold mass or mound is physically separated, the cells find their way back to re-unite. Studies on Physarum have even shown an ability to learn and predict periodic unfavorable conditions in laboratory experiments. Professor John Tyler Bonner, who has spent a lifetime studying slime molds argues that they are "no more than a bag of amoebae encased in a thin slime sheath, yet they manage to have various behaviours that are equal to those of animals who possess muscles and nerves with ganglia – that is, simple brains."

Atsushi Tero of Hokkaido University grew the slime mold Physarum polycephalum in a flat wet dish. He placed the mold in a central position representing Tokyo, and he placed oat flakes in the dish corresponding to the locations of other major cities in the Greater Tokyo Area. As Physarum avoids bright light, light was used to simulate mountains, water and other obstacles in the dish. The mold first densely filled the space with plasmodia, then thinned the network to focus on efficiently connected branches. The network strikingly resembled Tokyo's rail system.

I hope you didn't get fungal rot.
