| author | (Cleland) E.-J. Gilbert |
| english name | "Pale Yellow Limbed-Lepidella" |
| intro | This description is based on that of Bas (1969). |
| cap | The cap of Amanita sublutea is 30 - 45 mm wide, convex to plano-convex with a slightly depressed center, pale buff, viscid when moist, slightly appendiculate, with a nonsulcate margin. The cap is covered with vague and very thin, felted, concolorous, inconspicuous, crust-like remnants of volva over the center. |
| gills | The gills are subdistant, narrowly adnate, rather broad, and white. The short gills are truncate to obliquely truncate and rather scarce. |
| stem |
The stem is 35 - 45 × 6 - 10 mm, equal, exannulate, with inconspicuous, very narrow, pale, submembranous volval limb on the margin of the bulb. |
| spores | The spores measure (11-) 11.5 - 13 (-13.5) × 6.5 - 7.5 (-8) µm and are amyloid and elongate (rarely cylindrical, sometimes slightly obovoid). Clamps are absent at bases of basidia. |
| discussion |
Amanita sublutea was originally described from the state of South Australia. No associated plants were listed by Cleland. Bas placed A. sublutea in his stirps Preissii (see A. preissii). For purposes of history and other comparisons, the reader may also wish to check A. kammala Grgur.—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 data is derived from the revision of Bas (1969). from Bas (1969): Basidiomes small. | ||||||||
| pileus | from Bas (1969): 30 - 45 mm wide, pale buff (slightly deeper than Warm Buff), convex to plano-convex with slightly depressed center, viscid when moist; context white; margin nonsulcate, slightly appendiculate; universal veil as crust-like remnants over disc, vague, very thin, felted, concolorous(?), inconspicuous. | ||||||||
| lamellae | from Bas (1969): narrowly adnate, subdistant, white, slightly ventricose, up to 6.5 mm broad, with entire edge; lamellulae truncate to obliquely truncate, rather scarce. | ||||||||
| stipe | from Bas (1969): 35 - 45 × 6 - 10 μm, white with slight buff tinge near base, cylindric, subflocculose above, subfibrillose-subglabrous below; bulb marginate-globose, 14 - 20 mm wide; context white; exannulate; universal veil as inconspicuous very narrow limb on bulb margin, submembranous, pale. | ||||||||

none recorded. | ||||||||
| pileipellis | from Bas (1969): in two layers, with suprapellis 50 - 100 μm deep and gelatinized; filamentous hyphae 1.5 - 5μm, interwoven. | ||||||||

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.
