Features
Macroscopic characteristics
The up to 3 cm wide, often krausig -lobed shaped and very brittle headboard is white-yellow, grayish or pale brown in color. Hutlappen the externally coated by the spore- producing fruit layer. The 2-15 (-25 ) cm high, deeply furrowed longitudinally ribbed handle and has a tougher consistency and is white in color. He's down bulbous and tapering to the tip. Interior is crisscrossed the stem of irregular and elongated cavities. Young specimens have a pleasant, old, however, a strong sweet smell and taste. The spore powder is white.
Microscopic characteristics
The spores are hyaline, elliptical-shaped, smooth and have a large oil drops. They measure 16-20 × 10-12 microns. They mature in cylindrical and about 240-290 × zoom 15-18 micron sized tubes. The sterile juice hair in the fruit layer are filiform, slightly clavate at the tip and have cross walls.
Artabgrenzung
The habitual and identical in color, but smaller Milky White Lorchel ( Helvella lactea ) can be microscopically hardly be distinguished from the Autumn Lorchel. In addition, the Autumn Lorchel with the dünnfleischigen structure, the lobed head part and the grooved handle is very similar to the closely related Pit Lorchel. However, this headboard has a gray- black color, with the exception of albino forms. In addition, the fruit layer sterile surfaces are facing away, smooth, while the fall Lorchel are coated fine fluffy. This is caused by hair similar elongated cells. Sometimes Lorcheln also be confused with different types Morel - but the latter have a more or less honeycombed structured headboard.
Ecology
The Autumn Lorchel is to find the way and roadsides from July to November on. She likes rich, moist places with foliage and can grow in the undergrowth of forests as well as in ditches or along forest edges of meadows. It grows in the mountains and in the plains, but preferably in deciduous forests in the middle range. Often they can be found in communion with cup Lingen and they usually appear in large groups. The soil is neutral to calcareous.
Dissemination
In Europe it is widespread in the north they should be absent from the 62nd degree.
In Switzerland, it is north of the Alps, so the plains from Lake Geneva to Lake Constance, very common. In the Alpine region itself and on the southern side it was detected only sporadically. On the Red List it is currently under "low concern" listed (as of 2009 ).
Importance
To use the Autumn Lorchel as edible mushroom among mushroom connoisseurs there is no clear opinion. Some advise against the consumption, therefore, particularly sensitive people should avoid eating this mushroom. Others recommend to use the fruiting bodies only after boiling or drying. Definitely make sure to pick up any over-aged specimens, as well as externally flawless fungi are often already been spoiled under the headboard. Also on various small animals in the cavities should be respected.
