The poisonous yellow-scaly or yellow-flaky woolly stem umbrella ( Lepiota magnispora , syn. Lepiota ventriosospora ) is a species of mushroom from the family of mushroom relatives (Agaricaceae). The species is very similar to the more common woolly puss, but differs through the vivid yellow to ocher-colored velum and the large, spindle-shaped spores. The fruiting bodies appear from June to November in mixed coniferous and deciduous forests.
features
Macroscopic features
The 3–6 (8) cm wide hat is initially conical and often bluntly hunched and later shields. It is covered with cinnamon-brown, concentrically arranged scales on a yellow-ocher ground. The almost velvety smooth middle of the hat is also darker ocher brown to reddish brown in color, but less clearly delineated than in the woolly pussed umbrella . The brim of the hat is fringed with a yellowish velum.
The relatively narrow, thin, whitish to pale cream-colored lamellae do not touch the stem. The spore powder is white and dextrinoid .
The 5–8 cm long and 0.3–0.8 cm wide stem is whitish, but beneath the indistinct ring zone it is covered with a yellowish velum and thus appears yellow-shaggy. A real ring is missing. With age, the stem can become bald and darken, especially towards the base.
The thin, whitish to yellowish flesh smells faintly mushroom-like and tastes mild, but sometimes also scratchy and disgusting. The smell can sometimes be reminiscent of the stink umbrella or luminous gas.
Microscopic features
The long spindle, 14.5–17.5 (25) µm long and 4–5.5 µm wide spores have a distinct hilar depression, which is a small depression in front of the apiculus .
Species delimitation
The yellow flaky woolly umbrella differs from the closely related woolly umbrella ( Lepiota clypeolaria ) by its yellowish velum and the larger spores. Also very similar is the white woolly stalked umbrella ( L. alba ), which is colored white in all parts and also has shorter spores. The shoed umbrella ( L. ignivolvata ), whose stem base turns red with age , also has a certain similarity .
ecology
You can find the saprobion table living yellow-flaky woolly umbrella in the deciduous and coniferous litter of coniferous or mixed deciduous forests. It occurs on both calcareous and acidic soils, the fruiting bodies appear from August to October. Common accompanying trees are red beeches, oaks and especially spruces.
distribution
The fungus has been found in North America (Canada, Mexico, USA), Asia (India, South Korea, Turkey) and Europe. It is widespread throughout Northern, Western and Central Europe. Overall, it is relatively rare in Western Europe, the Benelux countries and Great Britain, it is widespread in Central Europe but also not very common, while it is quite common in southern Scandinavia. In Norway the distribution area extends up to the 69th parallel. There is little information on the eastern and south-eastern distribution.
meaning
The yellow flocked woolen stem umbrella is suspect and, like all small umbrellas with an immovable ring, should not be collected for food purposes.
