name	Amanita inodora
name status	nomen acceptum
author	(Murrill) Bas
english name	"Odorless Limbed-Lepidella"
synonyms	≡Amanita roanokensis f. inodora (Murrill) Murrill. 1946. Lloydia 9(4): 330. ≡Venenarius roanokensis f. inodorus Murrill. 1946. Lloydia 9(4): 324.
intro	This description is based largely on that of Bas (1969).
cap	The cap of Amanita inodora is about 30 - 60 mm wide, convex to plano-convex, white, dry, appendiculate, with a nonsulcate margin. The cap is covered with very thin, inconspicuous, adnate, submembranous-felted to subpulverulent, small to rather large patches, or a more or less continuous, thin crust.
gills	The gills are crowded, narrowly adnate, adnexed or free, and white. The short gills are obliquely truncate.
stem	The stem is short, about 35 - 55 × 10 - 16 mm, solid, white, exannulate, and without distinct remnants of volva (in the material seen by Bas). The stipe has a pronounced marginate bulb that is obovoid to napiform (about 20 - 30 × 15 - 25 mm). There is also a fluffy annular zone near the apex or near the middle, but no membranous annulus.
odor/taste	The fruiting body is odorless.
spores	The spores measure (11-) 11.5 - 13.5 (-15.5) × 3.5 - 4.5 (-5) µm and are amyloid. Clamps are not found at bases of basidia.
discussion	Amanita inodora was originally described from Florida, U.S.A. in association with oak and in mixed woods. Coker collected the species in South Carolina. Bas placed this species in his stirps Roanokensis (see A. roanokensis Coker. —R. E. Tulloss

The editors of this site owe a great debt to Dr. Cornelis Bas whose famous cigar box files of Amanita nomenclatural information gathered over three or more decades were made available to RET for computerization and make up the lion's share of the nomenclatural information presented on this site.

intro

The following text may make multiple use of each data field.

The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material.

The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate.

Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain.

The following text is derived from the revision of Bas (1969) and other sources as cited in the text.

Bas (1969): Basidiomes small to medium, rather thickset.

lamellae

Bas (1969): narrowly adnate to adnexed to free, crowded, white, up to 9 mm broad; lamellulae obliquely truncate.

stipe

Bas (1969): 35^± - 55^± × 10^± - 16^± mm, white, granular above, flocculose below; bulb 20^± - 30^± × 15^± - 15^± mm, conspicuous, obovoid to napiform, marginate; context solid, white, firm; partial veil lacking or as fluffy, apical to median, annular zone (apical to median); universal veil lacking or indistinct.

discussion

Bas (1969): "Because of the shape of the bulb and the nature of the volva the types of A. roanokensis and its forma inodora are so much different in appearance that it is difficult to believe they represent forms of a single species.

"When it turned out that the patches of the volva on the cap have a distinct, membranous outer layer in roanokensis and not in that of forma inodora, it even seemed as though they were not closely related. However, in the specimens of Coker 13718, a collection which is described by Coker as odorless and which at first sight strongly resembles the type of A. inodora, the thin patches on the cap appeared to have a thin, submembranous, outer layer, just as in A. roanokensis. Therefore, in the type of A. inodora the outer, membranous layer of the patches of the volva has disappeared. In fact, there are some patches on the the cap of the type specimen of A. roanokensis to which the same has happened.

"Nevertheless, the rather small size, the distinctly marginate bulb, the relatively incoherent remnants of the volva on the cap, the larger inflated cells in these remnants, the lack of any trace of a volval limb on the margin of the bulb, and the somewhat smaller spores led me to decide to raise Murrill's 'forma inodora' to specific rank.

"Since Murrill described the true A. roanokensis as a new species (A. watsoniana) and placed his A. roanokensis together with the forma inodora in a group of species with friable volva (Murrill, 1948: 100) it would seem that A. roanokensis sensu Murrill is probably a form of A. inodora with a smell!"

Spore data for collections
provisionally identified as: Amanita inodora (Murrill) Bas

Spore data sets and their composite

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.
