The two-colored sheath Streifling or shortly Two Colored Streifling ( Amanita umbrinolutea ), also Dunkelgezonter coniferous forest-Streifling is a species of fungus from the family of Wulstlingsverwandten (Amanitaceae).

features

A typical feature of the two-colored vaginal striated are the dark brown lamellar edges.
The volva of the bicoloured vaginal strip, which is close to the base of the stem, has rust-brownish spots.

Macroscopic features

The yellow-green to olive-brown hat has a diameter of 5 to 10 cm. With age, the clearly grooved one begins to fade out from the edge. The hat meat is thin. The lamellae are white with dark edges and the spore powder that precipitates shows no color reaction ( inamyloid ) when iodine solution is added . The stem is usually white and rarely tinted like the hat. The stem surface is finely flaky to slightly frilled. The sheath is whitish in color.

Microscopic features

The rounded to slightly elliptical spores measure 11–15 × 10–13 micrometers.

Species delimitation

The species can be confused with other vaginal strips and the green leaf agaric . The latter has a stem ring, grows exclusively in the deciduous forest and smells sweet like artificial honey when old or when it dries on.

Ecology, phenology and distribution

The two-colored sheath streifling grows from August to November in mountain coniferous forests. It is common locally in Germany. He loves acidic soils. In Europe, the species is mainly found in Sweden and the other Scandinavian countries.

Systematics

The species is often referred to in literature as Amanita battarrae and is known by this name. Amanita battarrae in the sense of the original description (also known as dark-zoned deciduous forest streifling ) is a stronger species without dark lamellar edges and stalk snaking and with a less two-tone, gray-tinted hat from the Mediterranean deciduous forest.

meaning

The two-colored vaginal strips are edible like all vaginal strips, but not particularly tasty. Since it takes a long time to cook, it is not recommended.
