Physarum pusillum is a small myxomycete (slime mould) producing minute, pale-coloured sporangia on decaying plant material and bark in humid woodland environments. Its name reflects its diminutive size relative to other Physarum species. Like its relatives, it goes through a plasmodial feeding stage before forming reproductive structures, and it is distributed across multiple continents.
