Many-headed Slime

Physarum polycephalum


'inhabits shady, cool, moist areas, such as decaying leaves and logs. It is sensitive to light; in particular, light can repel the slime mold and be a factor in triggering spore growth.'


tropical rainforest, 800m


I spotted this in pristine montane rainforest in the mountains near Pensiangan.

Fun fact! Slime mold is not a fungus (though it sometimes resembles one) but a soil-dwelling amoeba; a brainless, single-celled organism. There are more than 900 species of slime mold, in every color of the rainbow except a true green, because they lack chlorophyll. Despite lacking feet, slime molds can travel considerable distances. Although slime mold survives as a single-celled organism when food is abundant, when food is scarce, it combines forces with other slime molds, and work as a team, even signaling to each other to join forces and form a multi-cellular mass. Once the mass is formed, the cells reconfigure, change their shape and function to form stalks, which produce fruiting bodies. These contain millions of spores, which get picked up and transported by the wind or a passing insect or animal, to begin the process again as single-celled organisms.

That is even more amazing.
Such a large spread of slime mold and yet there are not much spotting of it in Borneo.

Thanks Chun. It spreads about 45cm or so across that rotting log.
