Features
Macroscopic characteristics
The fruiting bodies are quite small, as in the genus Psilocybe. The hat is usually curved, brown in color and often has a sticky surface. The hat skin can be removed with little or as a whole. A velum is present in some species. On mature fruit bodies, it remains mostly as fibrous patches exist on the hat surface or sometimes forming a ring. The fins are pale to dark purple - brown. They are widely grown, attached or bulged on a stick or run with a tooth on a stick down. They are usually wide and are removed to narrow. The handle is shaped thin and cylindrical. The meat does not turns blue in injury. The spore powder is light to dark brown in color.
Microscopic characteristics
The spores are elliptical or hexagonal and often flattened. They are smooth and have a thin or thick wall. They appear honey-colored to brown and usually have a distinct germ pore on. The spores are inamyloid. The cheilocystidia are usually more or less bottle-shaped. Pleurocystidia missing. The hat skin is formed from a cutis or Ixocutis. Buckles are present or absent.
Species delimitation
The species of the genus were asked a long time to the genus Psilocybe. Its fruit bodies have in case of injury on blue meat shopping.
Ecology
Deconica species occur saprobiontisch ago on wood and plant debris, on earth as well as manure and peat.
Determination
Of great importance in determining the deductibility of hat skin, namely whether it can be deducted as a whole as a thin, transparent layer. Moreover, the presence and expression of the velum is important. Sometimes it forms a hem at the edge of hat and a ring or ring zone on the stem. There is sometimes a fine dusty film on the entire hat surface ( Feinbefaserter bald head, Deconica ella casta ).
Based on the fin and the spore color Deconica section is divided into two groups: the group around the Feingerieften bald head (D. inquilina ) with thin-walled spores that appear light brown in mass, and usually pale at the age slats. The second group to the dry bald head (D. montana) has thick-walled spores and aged dark purple - brown fins.
The spores divide the genus by its size and shape. In many species, they are flattened so that the side view will be narrower than the front view. This difference can be various degrees of seriousness. For very shallow spores can be found in a preparation many who are on the wider side. When Rautensporigen bald head (D. phyllogena ), these can be more than 90 %.
Taxonomy
Deconica was described in 1870 by Worthington George Smith and placed as a subgenus of Agaricus. Petter Adolf Karsten combined the taxon in 1879 to the genus. For a long time the species were assigned to the combined earlier by Peter Kummer in 1871 genus Psilocybe.
In 2000, however, it turned out that the genus Psilocybe is polyphyletic in this view. On the one hand she was out of the blue border, hallucinogenic species such as the pointed cone bald head ( P. semilanceata ), on the other hand, the non- blue, non hallucinogenic species to the dry bald head (D. montana ) and the Dung- bald head (D. merdaria ) formed. This conception of the genus Deconica had, inter alia, Peter D. Orton. Agaricus Since constituted in the year 1960 montanus recognized lectotype should have been renamed inter alia P. semilanceata. Since the name Psilocybe is however quite closely related to the hallucinogenic species with numerous publications on the taxonomy, toxicity and legal aspects, beat Redhead et al. 2007 before the name to preserve for the hallucinogenic Psilocybe species of the genus and assign it the new lectotype P. semilanceata. This request was approved in 2009 by the Nomenclature Committee for Fungi unanimously. In the same year, the first simple recombinations to the genus Deconica.
The two genera Psilocybe Deconica and are only distantly related. Some authors, they are even placed in different families. The genus Deconica includes the sections of the genus Psilocybe Deconica and coprophila in their former opinion, as well as two species of the genus Melanotus.
