They are located at base on soil and leaf stem. Not mealy bug. When touched they are dry and tiny egg like. Found when watering. Earth very dry.

This looks to be a relative of slime mold, though we do not have this particular type in my region.

It is likely not a pathogen, itself. These types of organisms feed on bacteria. It can indicate a bacterial infection in the soil, though.

Treating with a fungicide will help, otherwise, the organism itself will act as a bactericide over time.
