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 material not directly from the protolog of the present taxon or (Bas 1969) is based on original research by R. E. Tulloss.
Bas (1969): Basidiome medium-sized, slender. |
| pileus |
Bas (1969): 50 - 60 mm wide, grayish-brownish olive to grayish olivaceous brown, broadly parabolic to planar, with pileipellis hardly visible and unpolished; context firm, white; marginnonsulcate, slightly appendiculate; universal veil as dense covering of brown pulverulent material, as shapeless to conic warts over disc, outside of disc region as continuous layer concolorous with pileipellis. |

| odor/taste |
Bas (1969): Odor not recorded except for the almond-smelling liquid emitted by broken stipe tissue. Taste bitter. |

tests |
none recorded. |

Bas (1969): 30 - 40 × 7.5 - 8 μm, mostly 4- or 2-sterigmate, sometimes perhaps 3- and 1-sterigmate; clamps lacking. |
| universal veil |
Bas (1969): On pileus: with pigment intracellular; filamentous hyphae 3 - 8 μm wide, scattered, inconspicuous; inflated cells globose to ellipsoid, more rarely pyriform or clavate or elongate, 20 - 60 μm [?long], rarely up to 80 & 55 μm, often brown, sometimes lacking pigment, usually in more or less anticlinal parallel chains (with anticlinal arrangement most easily seen in warts over disc and, elsewhere, in material closest to pileipellis), sometimes singly terminal; vascular hyphae lacking or very scarce. On stipe: not described. |
| stipe context |
Bas (1969): longitudinally acrophysalidic; acrophysalides clavate-fusiform, up to 350 × 40 μm, sometimes with conspicuous flat elliptical refractive bodies up to 25 μm wide in acrophysalides. |
| partial veil |
absent. |
| lamella edge tissue |
Bas (1969): filamentous hyphae rather scanty; inflated cells small, globose to pyriform to broadly clavate, up to 30 μm wide, in terminal chains. |
| basidiospores |
Bas (1969) from basidiomes with "mainly" 4-sterigmate basidia: [20/2/1] 8.0 - 9.5 (-10.5) × 4.5 - 5.5 μm, (Q = 1.55 - 2.05; Q = 1.85), colorless, hyaline, thin-walled, amyloid, elongate to cylindric, often subreniform; apiculus not described; contents subgranular, refractive; white in deposit.
Bas (1969) from basidiomes bearing basidia with "many" 2-sterigmate basidia (also with 4- and perhaps 3- and 1-sterigmate basidia): [10/1/1] 9.5 - 13.0 (-15.0) × 4.5 - 5.5 (-6.5) μm, (Q = 1.90 - 3.0; Q = 2.4).
RET: [100/5/3] (8.3-) 9.1 - 12.0 (-12.4) × (4.0-) 4.4 - 5.1 (-5.5) µm, (L = 9.6 - 11.1 µm; L’ = 10.3 µm; W = 4.7 - 4.9 µm; W’ = 4.8 µm; Q = (1.70-) 1.86 - 2.49 (-2.76); Q = 1.95 - 2.35; Q’ = 2.17), colorless, hyaline, smooth, ??, amyloid, elongate to cylindric, occasionally slightly constricted; apiculus sublateral, cylindric; contents
mono- or multiguttulate; white in deposit. |

| discussion |
Bas (1969): "The type consists of three more or less complete, dried specimens, which I have marked A-C, and a great number of fragments. Not all the specimens were collected at the same time. It is, however, impossible now to reconstitute the original collection.
"Specimen A, probably represented by the left and the right figures published by Beeli (1935: pl. 3 (fig. 6)) and the two right figures of those published by Gilbert (1941: tab. 68), seems to me to be the most typical specimen of the type collection: I have studied it extensively. Specimen B, represented by the middle figures on Beeli's plate and the left one on Gilbert's plate, has no mature spores. Specimen C has aberrant spores and basidia as mentioned above. The seven largest fragments of caps of the type collection have spores resembling thoe of specimen A.
"The aberrant spores of specimen C seem to be explained sufficiently by the occurrence of abnormal basidia, but as the type does not consist of a single collection it should be kept in mind that specimen C may belong to another taxon.
"Because of the greyish olive pulverulent cap, smell of almonds, and bitter taste, this tropical species from the Congo is very well characterized. On account of the more or less erect, parallel rows of brown cells in the remnants of the volva on the cap, lacking clamps, and elongate spores, it is placed here near A. cinereoconia. In appearance A. odorata resembles A. lanosa and A. lanosula in stirps Chlorinosma, occurring in the same region, but in those two species clamps are present and the elements of the volva are irregularly disposed." |
