  1. Amanita centunculus, from tropical forest, Singapore. |
| intro |
This description is based on the original description (Corner & Bas, 1962) and the treatment by Bas (1969. |
| cap |
The cap of A. centunculus is 50 - 60 mm wide, convex then plane, white, dry, with a nonstriate margin. The volva is present as a few, sometimes only three, large, flat, angular, white then brownish, felted, membranous, thick patches. |
| gills |
The gills are free, crowded, and white. The short gills are truncate or obliquely truncate. |
| stem |
The stem is 40 - 50 × 10 - 13 mm, shortly rooting base, becoming widely hollow, white, wholly finely floccose-pruinose, and more or less attenuate. Volval remnants on the base are at first white to brownish patches, later on obscurely and thinly peronate with fading remnants, and finally merely flocculose. |
| spores |
The spores measure 7.0 - 8.5 × (4.5-) 5.0 - 6.0 (-7.5) µm and are amyloid and broadly ellipsoid to ellipsoid to elongate ellipsoid. Clamps were not observed at bases of basidia. |
| discussion |
This species was described from tropical forest in Malaya. Bas placed the present species in his stirps Strobiliformis (see A. strobiliformis (Paul. ex Vitt.) Bertillon in Dechambre.—R. E. Tulloss |

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 data on this tab is predominantly derived from the revision by Bas (1969). | ||||||||

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.
