 1. Amanita farinacea, from plate in (Cooke 1890), Queensland, Australia. See note on image tab. |
| intro |
The following is based on the description of Bas (1969) with additional information on dimensions, colors, and textures from the original description. |
| cap |
The cap of Amanita farinacea is about 60 - 75 mm wide, whitish (orig. descrip.), plano-convex, with margin slightly incurved, probably viscid when moist, with a nonsulcate, appendiculate margin. The center is pulverulent-verrucose from remnants of the volva; and the margin has thin, pulverulent, crust-like areas. The original description of the entire mushroom was "wholly mealy." |
| gills |
The gills are crowded, free, moderately broad, white, and becoming yellowish. |
| stem |
The stem is about 70 - 100 × 12 mm, equal, white, exannulate, fibrillose or mealy (orig. descrip.), with a rather thick, subflocculose volval rim at the top of a (??)small, (??)subglobose bulb. |
| spores | The spores measure 9 - 10.5 × (6.5-) 7 - 9 µm and are subglobose to ellipsoid. Clamps are abundant at bases of basidia. |
| discussion |
Amanita farinacea was originally described from the state of Queensland, Australia. Bas knew it only from the type. Bas placed the present species in his stirps Grossa (see A. grossa (Berk.) Sacc. and felt that A. farinacea might be a synonym of A. ananiceps (Berk.) Sacc. He could find no microscopic difference between the two taxa. Indeed, all but one specimen of the type of A. ananiceps has a destribution of volval material on a smooth (nonaereolate) pileus that is quite reminiscent of A. farinacea. Because the former species original description lacks description of colors and because the bulb of the type of the latter is badly damaged in its type, Bas hesitated to propose synonymy of the two names. It is not clear to me whether Cleland, Gilbert, Wood, etc. have redescribed the same species.—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 text which follows is based on the revision of Bas (1969). The original description of the present species comprises a brief Latin diagnosis as follows: "Albus, fungus totus farinaceus. Pileo carnoso, convexo, applanato, (2½-3 ...[unc.], albido, verrucis erectis prominulis, praecipue disco ornato, margine tenui, velo adnato, frimbriato, stipite aequali (3-4 × ½ unc.), exannulato, farcto, albo, volva bulbosa, margine libero crispato. Lamellis liberis, sublatis, confertis, albo-lutescentibus. Sporis globosis, 10 μ diam. "On the ground. Brisbane[, Queensland, Australia]. (Bailey, 690)" from Bas (1969): Basidiomes of medium size, rather slender. Reid (1980) argues that Cooke and Massee altered the description of this species in comparison to the field notes and "rough pencil sketch" that are deposited with the holotype. For Reid's comments, see discussion data field, below. | ||||||||

| discussion |
from Bas (1969): "Amanita farinacea is very closely related to or identical with A. ananaeceps. It has similar spores, a similar pileipellis, and the same type of tissue in the volva, while in both species clamps are present. "Judging by the original descriptions, macroscopically the main difference is to be found in the remnants of the volva on the cap. In A. ananaeceps the cap has been described as areolate with an angular, conical wart on each area; and in A. farinacea, as entirely farinaceous with erect, slightly projecting warts, epecially at the centre of the cap. "Among the five type specimens of A. ananaeceps; however, there is only one in which the centre of the cap is areolate, which in this cae means that the warts of volva are situated on rounded elevations of the cap. I am fairly certain that these elevations have been caused by drying. In the other type specimens of A. ananaeceps small warts occur scattered over a nearly smooth cap, or else the cap is glabrous. "Unfortunately the type of A. farinacea consists of only one specimen with a badly damaged base of the stem while we do not know the original colours of the type collection of A. ananaeceps. I do not wish to identify the two species before more information is available from specimens collected at or near the two type localities." Bas assigned the present species to his stirps Grossa. Reid (1980): "The holotype of A. farinacea, accompanied by a rough pencil-sketch of the fresh specimen with field notes, is preserved at Kew. Reference to these notes raises the question as to why Cooke and Massee described the macroscopic features in the way they did. For example, they described the fungus as wholly mealy when in fact there is no evidence of this from the notes or specimen. They also described the cap as 'sprinkled with erect prominent warts, chiefly at the disc.' The field notes merely state 'Pileus white, warty and mealy. The veil torn and hanging in rags to the edge of the pileus.' Cooke and Massee seem to have overemphasized the mealiness and the prominence of the warts. The sketch merely shows a convex pileus with a number of small warts (16) at the centre and a very conspicuously appendiculate shaggy margin. It also shows the stem with a rim of volval tissue at the slightly bulbous base, but whether this is intended to indicate a volva with free 'crispate' margin is open to question. The gills were noted as being 'of a very light yellow shade.'" Reid further cites Bas' comments on possible synonymy and is in agreement—only going so far as to place the present name with a question mark in the synonym list for A. ananiceps while maintaining separate descriptions for the two taxa and keying them out separately. | ||||||||

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.
