Amanita ceciliae
''Amanita ceciliae'', commonly called snakeskin grisette and strangulated amanita, is a basidiomycete fungus in the genus ''Amanita''. First described in 1854 by Miles Joseph Berkeley and Christopher Edmund Broome, it was given its current name by Cornelis Bas in 1984. It is characterized by bearing a large fruit body with a brown cap across. The cap has charcoal-grey patches, which are easily removable. The stipe is long, white in colour, and there is no ring on it. It is slightly tapered to the top, and has irregular cottony bands girdling the base. The universal veil is grey. Spores are white, spherical in shape, non-amyloid, and measure 10.2–11.7 micrometres. The mushrooms are considered edible, but field guides typically advise caution in selecting them for consumption, due to risks of confusion with similar toxic species. ''A. ceciliae'' is found in woods throughout Europe and North America, where it fruits during summer and autumn.
== Taxonomy and etymology ==
''Amanita ceciliae'' was first described by Miles Joseph Berkeley, an English cryptogamist and clergyman, and Christopher Edmund Broome, a British mycologist, in 1854. It is placed in the genus ''Amanita'' and section ''Vaginatae''.〔 Section ''Vaginatae'' consists of mushrooms with special characteristics – such as the absence of a ring, and very few clamp connections at the bases of the basidia.〔
The name ''Amanita inaurata'', given by Swiss mycologist Louis Secretan in 1833, has also been used for this species. In 1978, the name was declared nomenclaturally incorrect according to the rules of International Code of Botanical Nomenclature. Other synonyms are ''Agaricus ceciliae'', ''Amanitopsis inaurata'' and ''Amanitopsis ceciliae''.〔 The present name, ''Amanita ceciliae'', was given by Cornelis Bas, a Dutch mycologist, in 1984.〔(【引用サイトリンク】url=http://www.mycobank.org/BioloMICS.aspx?Table=Mycobank&Rec=124200&Fields=All )〕
The species is commonly called "snakeskin grisette".〔(【引用サイトリンク】url=http://eol.org/pages/997383/names/common_names )〕 Another common name is "strangulated amanita", referring to the tightly clasping volva. It is also called Cecilia's ringless amanita after Cecilia Berkeley, the wife of M. J. Berkeley.〔 The name was meant "to record the services which have been rendered to Mycology by many excellent illustrations and in other ways".
