english name | "Wood's Lepidella" |
intro |
The following is largely based on the original description (Wood 1997). |
cap |
The cap of Amanita annulalbida is up to 110 mm wide, pale to dull cream, sometimes towards dull-buff, convex then plane, smooth, dry, with a nonstriate and slightly appendiculate margin. The volva is present as abundant with flat, fibrillose scales and concolorous to, somewhat more intensely colored to grayish. |
gills |
The gills are narrowly adnate to free, crowded or subdistant, thin, white to slightly off-white to slightly cream, with a concolorous edge. Short gills are not described. |
stem |
The stem is up to 130 × 18 mm, white, discoloring with age, smooth or a little fibrillose. The ring is membranous, persistent, flared, striate above, and white to cream. The bulb is not abrupt, not with a distinct margin, and narrowing downward with a broadly rounded bottom. The bulb does not have a free volva and mostly without volval remains. In some cases, the stem has indistinct zones or friable granular remains, particularly in younger specimens. |
spores |
The spores measure 8.7 - 10.5 (-11.4) × (5.5-) 6.0 - 7.5 (-8.4) µm and are ellipsoid and amyloid. Clamps are absent at bases of basidia. |
discussion |
Wood describes the mushroom as occurring in sclerophyll forests, "tall open forests," and under Allocasuarina littoralis from the state of New South Wales, Australia. A sclerophyll forest in the Australian bush is a forest of hard-leaved plants including Eucalyptus in the overstory (wikipedia). Wood places this species in Bas' stirps Straminea, which seems appropriate. |

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 based entirely on the protolog of this species, which does not meet contemporary standards for Amanita taxonomy. | ||||||||
pileus | protolog: up to 110 mm wide, pale to dull cream, sometimes near buff [11B2(MP)-13B6(MP)-13D8(MP)], convex then planar, smooth, dry; context not described; margin "slightly appendiculate," "not pellucid striate"; universal veil as flat fibrillose scales or patches [per figure], abundant, concolorous with pileus or somewhat more saturated or grayish. | ||||||||
lamellae | protolog: narrowly adnate to free, close to crowded, white to off-white to pale cream, narrwp. with concolorous edge; lamellulae not described. | ||||||||
stipe | protolog: up to 130 × 18 mm, white, discoloring with age, smooth to subfibrillose; bulb "moderately swollen," "rounded"; context not described; partial veil membranous, persistent, flared, white to cream, superior [per figure], striate above; universal veil often absent, sometimes with indistinct zone or friable granular remains parricularly in younger specimens. | ||||||||
odor/taste | neither recorded. | ||||||||
macrochemical tests |
none recorded. | ||||||||
pileipellis | not described. | ||||||||
pileus context | not described. | ||||||||
lamella trama | not described. | ||||||||
subhymenium | protolog: inflated cells slightly inflated, except when immediately adjacent to basidium and then slightly to distinctly inflated. | ||||||||
basidia |
protolog: 50 - 60 × 11.0 - 15.0 μm; clamps absent. Note: Only 2-spored basidia are illustrated.—ed.] | ||||||||
universal veil | protolog: On pileus: filamentous hyphae 5.0 - 8.0 μm wide; inflated cells dominant, 35 - 45 μm [long?]. | ||||||||
stipe context | not described. | ||||||||
partial veil | not described. | ||||||||
lamella edge tissue |
protolog: sparse to fairly abundant [in material examined], inflated cells 20 - 34 × 22 - 25 μm, broadly clavate [per figure]. [Note: Sterile.—ed.] | ||||||||
basidiospores | from protolog: [-/-/-] 8.7 - 10.5 (-11.4) × (5.5-) 6.0 - 7.5 (-8.4) μm, (est. Q = 1.32 - 1.52; Q = 1.36 - 1.58), amyloid, ellipsoid; apiculus [per figure] sublateral and cylindric or subcylindric; contents not recorded; color in deposit not recorded. [Note: Data provided is not sufficient to permit generation of a sporograph. A conservatively estimated range of Q is provided so that an approximate sporograph could be generated; however, note that the spore length and width data used to generate the approximation produce results incompatible with the published range of Q. This type of problem is found repeatedly in Wood's monograph.—ed.] | ||||||||

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.
