Inocybe geophylla
Erdblättriger crack fungus ( Inocybe geophylla )
The Erdblättrige crack fungus or fungal Silky crack ( Inocybe geophylla ) is a common poisonous mushroom of the family veil Ling relatives ( Cortinariaceae ). The fruiting body is small, white and with gebuckeltem hat.
Features
The hat reached 1-4 inches in diameter and is initially conical before it spreads to a domed shape with a pronounced hump. The surface is white or cream colored and fibrous silky. The Hutränder are young, inflected before Aufschirmen and connected to the stem by a hair veil - part shell ( Cortina ). You are at the age partly bent and can tear (→ " crack mushroom" ). The thin stem is 1-6 inches high and 3-6 mm thick. The Cortina does not leave a ring. The forced stationary blades are attached to the stem or nearly free-standing and young cream before ausdunkeln with the maturing spores to a brownish, eponymous natural color. The cutting edges are bulging shape and remain white. The spore powder print is ocher brown. The meat tastes schärflich. The faint smell was compared with flour or moist soil or even described as semen table.
The ellipsoid to almond-shaped spores are smooth and measure about 7.5 to 10 4.5 to 6 microns. There are numerous crystal -bearing ( metuloide ), swollen at mid-length and truncated Endig shaped cystidia of up to 70 to 20 microns available.
Artabgrenzung
The style white pink crack fungus ( Inocybe whitei ) turns red when pressure and injury. The White crack fungus ( Inocybe fibrosa ) has larger and heavy-built fruiting bodies. There are other sites that may at first glance like small white mushrooms from other genera, but differ markedly in odor, spore color or other characteristics.
Distribution and ecology
The Erdblättrige crack fungus is common and widespread in Europe and North America. He lives in mycorrhizal symbioses in deciduous and coniferous forests and is lime-intolerant. He bears fruit from June to November in grassy places near paths or watercourses or often richer, bare earth that has been churned out on roadsides.
Toxicology
How many crack mushrooms contains Inocybe geophylla muscarine. The symptoms are those of a muscarinic poisoning, including greatly increased salivation, perspiration ( sweating) and watery eyes within 15 to 30 minutes after ingestion. At high doses, these symptoms of abdominal pain, severe nausea, diarrhea, blurred vision and shortness of breath can be followed. The poisoning symptoms usually resolve within two hours in general. Delirium not occur. The specific antidote is atropine. Through the timely onset of symptoms and the induction of emesis for removal of fungal material is advisable. Deaths due to the consumption of this type are not documented. The fungus is due to its small size of mushroom pickers often ignored.
Taxonomy
The official first description of the species as Agaricus geophyllus found in a work published in 1801 the mycologist Christian Hendrik Persoon. Paul Kummer gave him in his 1871 published " leader in the mycology " its current scientific name. Be Kind epithet is derived from the ancient Greek words " geo " means " earth" and " phyllon " for "leaf" from.
There are described various varieties, including var lateritia with reddish fruiting bodies. Also the Purple Silky crack fungus ( Inocybe lilacina ) has been and is partly as the variety lilacina or violacea out. But Phylogenetic genetic analyzes show a clear delineation of Inocybe geophylla.
