intro |
The following is based on the description of Bas (1969). |
cap |
The cap of Amanita ananaeceps is about 60 - 100 mm wide, probably convex to plano-convex, with a nonsulcate, appendiculate margin. The original color was reported by Bas unknown, but possibly whitish. The cap is covered with small, conical to shapeless warts. The original description states the warts are placed on areolae. Bas' opinion was that this was occasional occurrence due to weather conditions. His view was supported by the fact that only one specimen in the type collection appears to have been areolate. |
gills |
The gills are probably crowded and moderately broad. |
stem |
The stem is about 70 - 110 × 10 - 14 mm, equal or slightly tapering upward, and exannulate; remnants of volva are lacking or forming a slight, subfloccose rim at the top of the stipe's bulb, which is short marginate to submarginate, and napiform to ellipsoid. The stipe is exannulate or bears a submembranous-felted, subapical annulus. |
spores |
The spores measure (9-) 9.5 - 11.5 × (6.5-) 7 - 8 (-8.5) µm and are amyloid and broadly ellipsoid. Clamps are present at bases of basidia. |
discussion |
The species was originally described from Tasmania. Bas placed this species in this stirps Grossa (see A. grossa (Berk.) Sacc.). Bas thought the present species might be a synonym of A. farinacea (Cooke & Massee) Cleland & Cheel.—R. E. Tulloss |

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 largely derived from the revision of the type by Bas (1969). from type study of Bas (1969): "Basidiomes medium to large, rather thickset." | ||||||||
pileus | Bas (1969): 60 - 100 mm wide, original color not recorded, probably convex to plano-convex; context not recorded; margin nonsulcate, appendiculate; universal veil as small, about 1.5 - 3 mm wide, conical to shapeless warts, "in one young specimen at centre of cap each wart on a 4 - 6 mm wide, rounded elevation." | ||||||||
lamellae | Bas (1969): probably crowded and moderately broad. | ||||||||
stipe | Bas (1969): about 70 - 110 × 10 - 14 mm, equal or slightly tapering upward, furfuraceous to fibrillose; bulb short to elongate, marginate to submarginate, napiform to ellipsoid; context not recorded; partial veil submembranous, apical, felted, detersile; universal veil lacking or forming slight subfloccose rim at top of bulb or subverrucose zone at top of bulb and base of stipe. | ||||||||

none recorded. | ||||||||
pileipellis | Bas (1969): filamentous hyphae 3 - 5 (-8) μm wide, interwoven, locally with yellowish refractive contents, gelatinized near surface; vascular hyphae present. | ||||||||

discussion |
from type study of Bas (1969): "Colors are not mentioned either in the protolog or on labels or sheets of type specimens. From Berkeley's comparison with A. nitida we may assume that he probably thought the colors to be whitish. "The name of this species is somewhat misleading. The wart-like remnants on the cap are not very conspicuous. It is only at the center of the cap of one of the type specimens that these warts occur on rounded elevations of the trama of the cap; the other four caps are practically smooth. I think that these elevations are artificial developing especially when young caps carrying wart-like remnants are poorly dried. "At first sight the elements in the small warts on the cap appear to be irregularly disposed. It seems, however, that especially in the warts at the center of the cap the rows of cells and elongate elements show a preference for an erect position. In that case A. ananaeceps would take an intermediate position between the bulk of the clamp-bearing species of subsection Solitariae and the small group of clamp-bearing species in which all the elements of the volva seem to be irregularly disposed. "Amanita farinacea is probably identical with A. ananaeceps. "Amanita grossa differs from the present species especially in its very sturdy habit and more felted volva." Bas (1969) assigned this species to his stirps Grossa. | ||||||||

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.
