Extract from Wikipedia article: Mucilago crustacea is a form of slime mould, in the monotypic genus Mucilago, in the family Didymiidae. Due to its visual resemblance to canine vomit, it is known colloquially as the "dog sick slime mould" or "dog sick fungus", albeit that slime moulds are not true fungi.
Mucilago crustacea is a species of slime mold that belongs to the class Mycetozoa. It is characterized by its crust-like plasmodium and sporangia that are typically yellow to orange in color. In St. Petersburg, Leningrad Oblast, and north-western Russia, Mucilago crustacea has been found in various habitats, including forests, grasslands, and urban areas. The species is known to thrive in moist environments with rich organic matter, such as leaf litter and decaying wood. Records from the region indicate that Mucilago crustacea typically fruits in late summer to early fall, with sporangia often forming on vegetation, soil, and other surfaces.
