The Orange-yellow, orange brown or saffron vaginal Streifling ( Amanita crocea ) is an edible mushroom species from the family of Wulstlingsverwandten .
features
Macroscopic features
The hat reaches 5–10 cm in diameter and has a conical or bell-like shape when young, which later spreads from a domed to a flat shape with a hump. It has a smooth, bald, shiny, yellow-orange to orange-brown hat skin with a light apricot note in the middle and a grooved edge. Occasionally, shell remains remain on the hat. The meat is thin and fragile, has no characteristic smell or taste and shows a wine-red color reaction with phenol . Syringaldazine tests for laccase are positive. The lamellas are tightly packed and free from the stem, are cream-colored with a slight salmon-colored or pinkish reflection and have bulbous edges. The spore powder is white and does not show any color reaction with iodine reagents ( inamyloid ). The stem becomes 10–15 cm high, has a slim, tapering shape and is hollow, at least when old. When young, it is covered by a woolly or felted structure that later tears into fine scales and finally forms a rattled pattern. The stem surface underneath has a slightly paler color than the brim of the hat and the fiber structure on it is initially an even paler color, which later becomes significantly darker. The stem is in a thick, bag-like, lobed sheath ( volva ), which is whitish on the outside and hat-colored on the inside, and has no ring .
Microscopic features
The white, roundish (ratio of longest to narrowest diameter between 1.07 and 1.10, rarely up to 1.11) spores measure 8–12 (–18) micrometers in diameter and have a smooth surface. There are no buckles on the basidia .
Species delimitation
It can be confused with other similar and edible vaginal strips. The reddish brown sheath streifling ( A. fulva ) is slender, smaller and more likely to be found in conifers such as spruce and not in alder, ash, hornbeam, hazelnut and poplar. In addition, in contrast to A. fulva , the meat shows no color reaction with phenol. The yellow vaginal stripe ( A. flavescens ) differs in its somewhat elongated spores (length-to-width ratio usually over 1.12), a clear 2-layer cap skin, at least in ripe fruiting bodies, and only forms mycorrhiza with birch trees. The deadly cape mushrooms have smooth capped edges and ringed stems, whereby the ring can also be lost with age.
ecology
It grows in a mycorrhizal symbiosis with trees in coniferous and deciduous forests , preferably with birch trees and on acidic soils, and fructifies from June to November, mainly in summer. Mycorrhizal partners can be birch, oak, alder, spruce, hornbeam, hazelnut and poplar.
distribution
It is common in Europe , North America ( USA , Mexico ), Japan and in the Russian Primorye region on the Sea of Japan .
Systematics and taxonomy
It is the section of the lining pieces ( Vaginatae the genus) Wulstlinge assigned or Amanita mushrooms (Amanita). In 1982 Henri Romagnesi described the subnudipes variety , which is distinguished by a bare stem and microscopic characteristics. There are still undescribed species of their own that are currently collectively known as Amanita crocea.
meaning
The orange-yellow vaginal striated is used as an edible mushroom . It is poisonous raw and edible well cooked.
