Verpa bohemica
Wrinkle - Verpel ( packaging bohemica )
The wrinkle or Bohemian Verpel ( packaging bohemica ) is a species of fungus in the family Morchelverwandten. The rugose - wrinkled cap is only attached to the stem tip, the stem filled cottony young and later chambered hollow. The ascomycete fruktifiziert in spring, is stationary common in lowland forests on calcareous soils in southern Germany, but otherwise rare.

Features
Macroscopic characteristics
The wrinkle - Verpel forms up to 15 cm high fruit body ( morchelloide Komplexapothecien ), which are divided into the pileus and stipe. The approximately 2-5 cm high and 2-3 cm broad hat sits bell-shaped or roll-shaped on the stalk. It is grown only on the rounded apex of the stem and hangs down otherwise clear of the stem. The hat surface is irregularly wrinkled / structured brain- like or with protruding longitudinal and transverse ribs between them, their color ranges from yellow to ocher to dark brown. The ribs are often darker. The Hutunterseite is against contrasting whitish to ocher. The cottony young stuffed stem is hollow and chambered in age is long up to 15 cm. He has only a whitish, later yellowish to ockerliche colors and is covered with flaky kleiigen, sometimes arranged in a ring scales. The waxy brittle and slightly chewy meat smells and tastes normal.
Microscopic characteristics
Remarkable are the tubes in which mature only 2 giant spores. The spores are hyaline, long - cylindrical, sometimes slightly curved, smooth-walled, and measure 60-90 × 15-18 microns. The tubes in the fruit layer are also interspersed with filiform paraphyses.
Artabgrenzung
The Foxglove Verpel has a smooth or at most slightly wrinkled cap. In addition, the wrinkle - Verpel similar to morels, especially the cap - Morel. At The latter, however, about half of the cap is fused with the stem tip and the cap has a pitted - längsgerippte surface structure. The stem is completely hollow, even in young specimens, and outside strikingly grained granulated obtain. Both in the thimble - Verpel as well as the morels are seen under the microscope, 8- sporige hoses.
Ecology and phenology
The wrinkle - Verpel is a Bodensaprobiont. It grows in warm regions lights deciduous forests, floodplains, thickets and hedges mainly on calcareous soils, but also on basalt and glacial till of Jungmoränen.
The fruiting bodies appear in Central Europe from April to May, in floodplains often in large numbers. However, the species non fruktifiziert each year.
Dissemination
The species occurs from the Mediterranean and Black Sea area off to northern Norway, but is absent in Western Europe and in the north of Germany and Poland.
Importance
The wrinkle - Verpel is edible, though not declared the author Hans E. Laux as edible mushroom. It is generally recommended to protect the fungus because of its rarity. For dining value Gisela Lockwald writes in her mushroom cookbook that although the fruiting bodies are agreeable taste like mushroom, but can miss each morchelähnliche flavor. Therefore, and because of the nature protection discourages them from gathering.
System
The species is questioned by some authors as the only species in the genus Ptychoverpa.
