Slime molds

Phylum: Mycetozoa
Class: Myxomycetes
Order: Physarales

Species on page

Family: Physaraceae
Insect-egg slime (Leocarpus fragilis)
Deer vomit (Fuligo septica)
Physarum pusillum

Family: Didymiaceae
White-footed slime (Diachea leucopodia)

Family: Tubiferaceae
Red raspberry slime mold (Tubifera ferruginosa)
False puffball (Reticularia lycoperdon)

Family: Ceratiomyxacea
Honeycomb coral slime mold (Ceratiomyxa fruticulosa)

Family: Family Arcyriaceae
