intro |
The following is based on the description of Bas (1969). |
cap |
The cap of Amanita conicobulbosa is 50 - 100 mm wide, convex to plano-convex or flat, sometimes plano-convex or convex with a slightly depressed center, grayish white to white to pale ochraceous buff, sometimes with brownish or grayish tinges, viscid when moist, glabrous and shiny in places when dry, with a nonsulcate, appendiculate margin. The cap is sometimes scattered with rather large, concolorous, low, subpyramidal warts with firm tips and somewhat felted-fibrillose base, decreasing in size towards the margin; sometimes the cap is entirely felted-fibrillose. The gills are crowded, just free to slightly adnexed, broad (6 - 13 mm), cream white, and turning pale buff with age. The short gills are scarce and probably attenuate. |
gills | From Dr. Bougher's photographs, the gills are white or whitish in mass. |
stem |
The stem is 75 - 125 × 10 - 22 mm, slightly tapering upward, solid, white or whitish, fibrillose-squamulose to subglabrous, somewhat striate at the top, with vague small scales or warts or some circularridge derived from the volva at the top of the bulb. |
spores |
The spores measure 10 - 13 (-14.5) × (5-) 6 - 7.5 µm and are amyloid and broadly ellipsoid to cylindrical. Clamps are present at bases of basidia. |
discussion |
Amanita conicobulbosa was originally described from the state of South Australia, Australia. Bas placed the present species in his stirps Rhopalopus.—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 material is derived primarily from the protolog of the present taxon and the revision of Dr. C. Bas (1969). Additional information comes from (Reid 1980). frp, Bas (1969): Basidiome medium to large, slender. | ||||||||
pileus | from Bas (1969): 50 - 100 mm wide, grayish white to white or pale ochraceous buff, sometimes with brownish or grayish tinges, convex to plano-convex, with slight depression over disc, viscid when moist, glabrous and shiny in spots when dry; context [white, at least 6 mm thick over stipe, "attenuating outwards" (per protolog)—ed.]; margin non-sulcate, appendiculate; universal veil sometimes as felted-flocculose covering of entire cap, occasionally as scattered low subpyramidal warts with firm tips and somewhat felted-fibrillose base and decreasing in size toward margin. | ||||||||
lamellae | from Bas (1969): just free to slightly adnexed, crowded, cream-white turning pale buff in age, 6 - 13 mm broad, ventricose; lamellulae scarce, "probably attenuate." | ||||||||
stipe | from Bas (1969): 75 - 125 × 10 - 22 mm, white or whitish, slightly narrowing upward, fibrillose-squamulose to subglabrous, somewhat striate at apex; bulb up to 75 × 35 mm, abrupt, elongate-fusiform to elongate-subconical; context solid, [white per protolog—ed.]; partial veil superior to median, moderately broad, pendent to appressed, white, submembranous-felted, striate; universal veil (limbus internus) as small scales or warts or some circular ridges at top of bulb. | ||||||||

discussion |
Reid (1980) argued for replacement of the lectotype designated by Bas (1969) for the present species. In attempting to supersede Bas' selection of lectotype, Reid makes indirect reference to article 9.17 of the ICBN, part (b): "The author who first designates a lectotype or a neotype must be followed, but that choice is superseded if...(b) it is in serious conflict with the protologue and another element is available that is not in conflict with the protologue...." Since both Bas and Reid accept the fact that the collection designated by Bas and the collection designated by Reid are in fact conspecific, Reid does not establish in the least that Bas' choice of lectotype is in conflict with the protolog. Therefore, Bas' choice must stand. According to Reid, documentation unavailable to Bas makes the non-lectotype collection a more thoroughly annotated one. t.b.d. | ||||||||

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.
