Amanita ceciliae: The Ultimate Mushroom Guide
About The Amanita ceciliae Mushroom
Amanita ceciliae 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 5–12 cm (2.0–4.7 in) across. This is a distinctive, often tall species. In young specimens, the cap is yellowy colored and has numerous fleecy grey patches, by maturity the cap loses most of its yellow tint and looks a duller brown, but often retains the fleecy patches. The cap margin may be paler than the center and is noticeably grooved. The stem has a fragile grey volva at the base.
Amanita ceciliae is considered an edible mushroom and used as food, although many field guides recommend avoiding eating it. Others recommend it as a good edible species. A study of 16 edible mushrooms was done to learn about their chemical compositions and antioxidant activities. Among these species, A. ceciliae and Pleurotus ostreatus were the two mushrooms that showed the most powerful radical scavenging activities.
Other names: Snakeskin Grisette, Strangulated Amanita.
Amanita ceciliae Identification
The cap is 75 - 110± mm wide, brownish-yellow at first, losing all yellow tints at maturity and becoming a sordid brown, subellipsoid at first, later campanulate, and often decorated with dark gray to blackish gray volval remnants. The cap's margin is distinctly striate.
The gills' are distinctly free at first and tend to become remote; they are sometimes forked or grown together in places. The short gills are abruptly truncate.
The stem 100 - 160± × 15± - 19± mm, whitish and narrowing upward. It is decorated with one or more rings of dark volval material (with its coloring changing as it does on the cap). The stem is not firmly stuffed and is often at least partially hollow. There is no ring on the stem. The remains of the volva on the stem's base usually take the form of a short, pallid, cup-like structure.
Odor and Taste
The original description of this species states that it lacks an odor and has a sweet taste.
Spores measure (9.5-) 10.3 - 14.9 (-25) × (8.6-) 9.5 - 14.3 (-25) m and are inamyloid and globose to subglobose (rarely broadly ellipsoid). A few "giant" spores are commonly found in amount of gill tissue. Clamps are not found at the bases of basidia.

Amanita ceciliae Taxonomy & 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 nomenclatural 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.
The species is commonly called "snakeskin grisette". 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".
