Features
Macroscopic characteristics
The fruiting bodies appear on the ground. The hat dünnfleischige reached 3-6 cm in diameter. It is curved to spread out and often has a strong, blunt hump on. The edge is still bent down in young specimens. The hat surface is finely scaly or tomentose, dry and dull. Your coloring is pale gray to gray- brown and gets lighter towards the edge. The firm, white flesh is radialfaserig - brittle and slightly floury taste and smell. The lamellae are grown bulged on a stick. Meat and fins yellowing slowly after injury and old age. The stem is 5-8 inches high and 8 to 12 mm thick and has a cylindrical shape to the often pointed, never thickened base. He is stuffed inside, fleshy and brittle. He has a relatively durable cottony to membranous ring, by which he is somewhat fibrous - flaky. The spore powder is white and shows with iodine reagents no color reaction ( not amyloid ).
Microscopic characteristics
The narrow ellipsoidal spores measure 4-5 × 2.5-3.5 micrometers.
Artabgrenzung
Most important distinguishing features are the ring on the stem and its association with willows. Among the difficult distinguishable grauhütigen Knight Lingen there is also the highly toxic tiger Knight (Tricholoma pardinum ) and also with the Brennendscharfen Knight (Tricholoma virgatum ) would be a dangerous confusion. Fins and flesh of the more common, also edible yellowing earth knight compact ( Tricholoma argyraceum ) slowly turn yellow and he is not only growing with willows. Tricholoma scoides has no ring.
Ecology and phenology
The Ringed Ritterlingsartige lives in European forests and parks - like in lowland forests - in acidic soils in mycorrhizal symbiosis with willow and birch.
He fruktifiziert June to October or December.
Importance
The mushroom is edible, but not very tasty and should be spared because of its rarity.
Systematics and Taxonomy
The species was first described scientifically in 1830 by Almfelt as Agaricus cingulatus. The scientific recognition of the new species, however, led only reference to this species description by Elias Magnus Fries in 1832 published work. In 1890 he was transferred from E. Jacobasch in the genre of the knight pieces ( Tricholoma ). He is expected within the genus to the section of the earth's knight pieces ( Atrosquamosa ).
