Didymium spongiosum, also known as dog sick slime mold, is a species of true slime mold in the order Physarales. [1] [2] Before reclassification in 2023 it was known as Mucilago crustacea. [3] Due to its visual resemblance to canine vomit, [4] it is known colloquially as the "dog sick slime mould" [5] or "dog sick fungus", [6] albeit that slime moulds are not true fungi. [6]

The fruiting body is yellow to white, becoming paler with time, and then blackening. [5]

It usually occurs on damp grass. [4] The species was described by P. Micheli ex F.H. Wigg. [4] [7]
