The gold dung mushroom or yellow dung mushroom ( Bolbitius titubans , syn. Bolbitius vitellinus ) is a type of mushroom from the family of dung mushroom relatives (Bolbitiaceae). The fruiting bodies appear on dung, straw and plant remains from May to November. The gold dung mushroom is not an edible mushroom.
features
Macroscopic features
The very thin fleshy hat is 2–6 cm wide, conical to ovoid when young, later bell-shaped and finally arched to spread out. The young, shiny, greasy, sticky surface is bright golden yellow to lemon yellow in color. Dry and with age, the hat pale yellow to ocher. The edge is furrowed and grooved, in old specimens almost to the middle.
The lamellas are narrowly attached to the handle and are rather crowded. They are pale yellow when young and turn rusty-yellow to rust-brown with increasing maturity, their edges are ciliated white. The spore powder is rusty brown.
The cylindrical, hollow and very fragile stem is 4–12 cm long and 0.3–0.6 cm wide. It is whitish to yellowish in color and flaky white frosted over its entire length and silky-fibrous. The tip of the stem is usually more yellowish in color. Even the very thin meat is whitish to yellowish and more or less odorless and tasteless.
Microscopic features
The elliptical spores are 10-14 µm long and 6-9 µm wide and have a germ pore. The basidia are truncated and the cheilocystids are bottle-shaped.
Species delimitation
The golden dung mushroom can hardly be confused because of its striking golden yellow color. Older blown-out specimens may look similar to the white dung mushroom ( Bolbitius lacteus ), which is milk-white from its youth , is rarer and grows in grassy areas.
Ecology and diffusion
The common gold dung mushroom can be found solitary to gregarious on fertilized soil and in nutrient-rich locations from May to November. It grows in grassy areas, rotting straw, on dung and compost heaps or on wood waste.
meaning
The gold dung mushroom is not an edible mushroom.
