The macroscopic description is based on the original description of Berkeley and Broome (1854).
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.
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 a mount of gill tissue. Clamps are not found at bases of basidia.
Amanita ceciliae is a European species that is incorrectly reported from many places throughout the world. In young material such as that depicted above, the cap is brown over the center and brassy elsewhere. Eventually, the cap becomes entirely brown.
The species is also known by the name A. inaurata Secr. ex Gillet, a later synonym. Fries used the name A. strangulata for this species, but his original description of A. strangulata states that it is a white species. According to Bas (1984), the Friesian name should be discarded as of unknown meaning. The Colombian and Mesoamerican species known as "ceciliae" or "inaurata" is A. sororcula Tulloss, Ovrebo & Halling. The North American taxa known under the above two names are several and, as yet, undescribed.

The microscopic data and information derived from macroscopic review of exsiccata derives from original research of R. E. Tulloss.
The Latin diagnosis and comments from the protolog (Berkeley and Broome 1854) read as follows:
"Pileo primum semielliptico, volva murina crassiuscula rimosa, demum basi irregulariter circumscissa marginata operto, dein campanulato; margine sulcato; stipite sursum attenuato spongioso farcto; annulo nullo."
"Allied to A. vaginatus, but without a distinct sheathing volva, and with the stem merely spongy within and not filled with delicate cottony fibres. In full-grown specimens there is only a slight mark showing where the edge of the pileus rested. It is allied to the veil-less species from the Himalayas. The name is intended to record the services which have been rendered to Mycology by many excellent illustrations and in other ways by Cecilia E. Berkeley."
from protolog: 76 - 102 mm wide, dingy yellow [at first —ed.], at first semiellipsoid, then campanulate and obtuse; contents not recorded; margin sulcate; universal veil absent or present as thick mouse-colored flat patches or warts or as warts with an acute peak, when present more or less forming a dense covering of pileus.
RET: based on exsiccatum of Perreau 475: 110 mm wide; margin striate (0.3R - 0.35R), nonappendiculate; universal veil paler than pileus surface in exsiccata, pallid at first, darkening with exposure and age (gray-brown to dark grayish brown with high points and ridges fuligineous to nearly black), as many warts, detersile, often leaving thin layer of detritus over much of pileipellis (observed microscopically in scalp section).
from protolog: quite free, at length remote, thick, sometimes forked or anastomosing, with interstices venous; lamellulae abruptly truncate.

from protolog: 102 × 19 mm, attenuated upwards, above silky, below squamulose from fragments of volva, transversely or obliquely rimose; contents spongy, with occasional cavities, "but by no means filled with floccose down"; exannulate; universal veil thick, mouse-colored, at length splitting irregularly "from slight prominence" at base of stem [i.e., leaving cupulate volva—ed.], "by no means vaginate" [i.e., not saccate—ed.].
based on exsiccatum of Perreau 475: 160± × 15± mm, narrowing upward, with fuligineous "flame" or zebroid pattern on grayish brown ground; exannulate.

Notes of C. Bas with type in K (King’s Cliffe, ix.1852 no coll. s.n.) give dimensions of spores as [10/1/1] 10.5 - 15.5 × 10.5 - 15.3 µm. In an accompanying collection from the type locality without other data (possibly an isotype per C. Bas’ notes), Bas recorded spores as follows: [11/1/1] (11-) 12.5 - 16 (-21) × (11-) 12 - 15.5 (-20) µm. I approximate the Q values for these two sets of measurements as 1.01 and 1.04.

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer;
and explanations prepared for this site talk about specimen-observer pairs associated with each data set.
Combining more data into a single data set is non-optimal because it obscures observer differences
(which may be valuable for instructional purposes, for example) and may obscure instances in which
a single collection inadvertently contains a mixture of taxa.
