We generally sterilize oatmeal in Pyrex test tubes but any small glass container can be used. Slime mllowing it to crawl away from the fungal contamination. You can also try growing your plasmodia outdoors in their natural habitat on the compost pile and feed them oatmeal, banana peels, leaves etc. Plasmodia produced in your old banana trays will produce sporangia in a few days when they run out of oatmeal or microorganisms to eat. The organisms we commonly find are Physarum compressum, P. gyrosum, Fuligo septica etc.
Slime molds are relatively easy to identify down to species.
Simply get the colored picture book and turn the pages. If anyone gets interested in such a project we could perhaps get out a publication. An updated list would be a great science project for school.
