Many clusters of these growing on the same Astelia nervosa plant, but not any others. In native bush beside non-public council access road.
Maybe a slime mold
Growing on a decaying Trametes on a log. In redwood forest.
Growing on cut end of log.
I'm thinking a slime mold. It looks like tapioca slime or brefeldia maxima. It appears to be growing on grass.
Protozoa are a diverse group of unicellular eukaryotic organisms, many of which are motile. Originally, protozoa had been defined as unicellular protists with animal-like behavior, e.g., movement. Protozoa were regarded as the partner group of protists to protophyta, which have plant-like behaviour, e.g. photosynthesis.
