The Daffodil Yellow Amanita ( Amanita gemmata , Syn. : A. junquillea ) is a toxic fungal species from the family of Wulstlingsverwandten (Amanitaceae).
features
The daffodil yellow amanita has a 3–10 cm wide, initially bell-shaped and later slightly domed to flattened hat . It is colored pale yellow to yellow-ocher, lighter on the edge than in the middle and there it is conspicuously grooved. The slightly greasy surface of the hat is covered with snow-white, flat and often irregularly distributed velum flakes . The tightly packed lamellas on the underside of the hat are white to pale yellow in color. The spore powder is white. The 5–10 cm long and up to 1 cm thick stem is thickened at the base with a bulging velum residue and a flocked belt. It is white to light yellow in color. The meat ( trama ) is white, odorless and tastes mild, somewhat nutty.
Species delimitation
Due to its appearance, it can easily be confused with the more common, slightly poisonous yellow cap mushroom , which has a characteristic potato sprout-like odor and sharply cut tuber edge. Also similar is the rarer Isabel-colored amanita with a deeply sunk volva . Darker colored specimens of this type of mushroom can also be confused with the very poisonous panther mushroom .
Ecology, phenology and distribution
The daffodil yellow amanita occurs in coniferous and deciduous forests in the northern hemisphere . It is a common mycorrhizal fungus of spruce or bearberry in the western United States and is often found on sandy and acidic soils. It appears as one of the first amanita under good conditions from the end of May, mostly from June to October. Its distribution area in Germany is quite scattered.
toxicology
The daffodil yellow amanita is relatively common, which is why the contradicting statements about its toxicity appear unusual. It is possible that there are different variants with different compositions of ingredients. Some of the fatalities from Chile, which were initially associated with the daffodil yellow amanita , are likely to be ascribed to the similar species Amanita toxica . The daffodil yellow amanita is said to have a hallucinogenic effect, presumably it contains ibotenic acid , muscarin and muscimol .
