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 is derived from the protolog and (Reid, 1980) and from original research of C. Rodríguez Caycedo and R. E. Tulloss. |
| pileus |
from Reid (1980): up to 50 mm wide, pale gray-brown fresh, brownish gray dried, at first stongly convex, becoming flattened; context white; margin smooth; universal veil as pale yellowish, thin, felty-pulverulent layer, tending to form indistinct "cobwebby scales" toward center, with scales less distinct in dried material, not retaining pigment in dried material. |
| lamellae |
from Reid (1980): white. |
| stipe |
from Reid (1980): up to 40 × 10 mm, white above, creamy yellow below partial veil; bulb clavate, up to 15 mm wide, abruptly pointed below; context white; partial veil membranous, well-formed, pendulous, faintly striate, creamy yellow; universal veil lacking. |

| basidia |
from Reid (1980): 40 - 45 × 8 - 12 μm, 4-sterigmate; clamps lacking. |
| universal veil |
from Reid (1980): On pileus: hyphae up to 8 μm wide, fairly frequent, thin-walled, hyaline, branched; inflated cells predominating, globose or ovoid, up to 55 × 45 μm, terminal, singly on short branches or in short chains "by inflation of hyphal segments," with such chains readily dissociating; clamps not seen. |
| stipe context |
not described in protolog. |
| partial veil |
not described in protolog. |
| lamella edge tissue |
from Reid (1980): inflated cells spheropedunculate or ovoid, up to 20 μm wide, terminal on short chain of hyphal segments, with these sometimes slightly inflated. [Note: This tissue misdescribed by Reid as cheilocystidia.—ed.] |
| basidiospores |
from protolog: [-/-/1] 7.0 - 9.2 × 5.0 - 7.0 μm,
(est. Q = 1.30 - 1.40), amyloid, ellipsoid; apiculus not recorded;
contents not recorded; color in deposit not recorded.
composite data from spores of material revised by CRC and RET: [40/2/2] (7.2-) 8.1 - 9.3 (-10.5) × (5.3-) 6.0 - 7.0 (-7.5) μm, (L = 8.7 μm; L' = 8.7 μm: W = 6.3 - 6.7 μm; W' = 6.5 μm; Q = (1.11-) 1.21 - 1.46 (-1.70); Q = 1.31 - 1.37; Q' = 134), colorless, hyaline, thin-walled, smooth, amyloid, broadly ellipsoid to ellipsoid, infrequently subglobose; apiculus sublateral, cylindric; contents granular to mono- or multiguttulate; color in deposit not recorded. |

| discussion |
from Reid (1980): "In the exsiccatae [sic] the base of the stem has dried in such a way as to suggest, quite wrongly, that it was marginately bulbous in the living condition."
The present species "is characterized by the peculiar thin felty-pulverulent yellowish layer of volval tissue which completely covers the cap."
Bas' annotations on his copy of (Reid 1978) indicate that he judged this species to be assignable to sect. Validae. We have followed this idea.
The collections Albertella s.n. (2.iv.2011), Albertells Back5b, and Albertella Back5 had entirely or almost entirely immature hymenia. In the latter case, no spores were found at all; in the other two cases, only three spores were found that presented in lateral view in each of the collections. Consequently, at present, our spore data [exclusive of that in the protolog and (Reid 1980)] is based on two collections.
Spore size and shape comparison by means of a sporograph is provided below for the present species and A. griselloides:
