Fuligo septica (Scrambled egg slime)

Occurrs as slimy to crust-like sheets or cushion-like iregular masses on stumps, logs, living plants, and wood mulches in landscapes. This slime mould first appears as a white to yellow slimy mass with various dimensions. The "flesh" transforms into a crusty, cake-like mass of darker and variable color. The brittle crust easily breaks away to reveal a dull-black spore mass. Fuligo septica produces the largest spore-producing structure of
any known slime mold.

Plasmodium:- bright yellow or white.

Sporangia:- Aethalia pulvinate, varying in size from 2 mm. to more than 30 cm., various shades of yellow but can also be  greenish, reddish, and brown to deep chocolate.

The sporangia are intricately coiled and anastomosing, but often more or less separated in the mass, with spaces in between;

The cortex can be thick or thin, a dense crust of lime or undeveloped Plasmodium, loose or firm, or absent entirely; with scattered deposits of lime-granules.

Capillitium:- scanty or abundant, consisting of a loose network of slender hyaline threads, more or less expanded at the axils, with fusiform or branching lime-knots, usually white but often yellow, or occasionally reddish or brownish.

Spores:- Purplish-brown smooth to minutely spiny
