BRIEF DESCRIPTION: This description is taken from Bas (1969) and the original description of C. A. Grgurinovic (1997).

The cap of Amanita kammala is up to 30 mm wide, plano-convex, possibly white with faint yolk-yellow tinges (color of the original material is unknown), probably viscid, with a nonsulcate and not or slightly appendiculate margin.  Volva remnants are not distinct on the single specimen known.

The gills are narrowly adnate, subdistant, rather broad, slightly ventricose, white.  The short gills are truncate.  Bas points out that there are yellowish refractive hyphae that may have given a yellow tint to the gills of A. straminea (see below) that are absent in the present species.

The stem is up to 35 x 3 mm and exannulate.  The stem has an ellipsoid emarginate (Grgurinovic) or marginate (Bas) basal bulb on the top of which is an upstanding submembranous fringe of volval material that stands off from the stem a short distance, but collapses on the stipe.

The spores measure (9.6-) 10.8 - 14.6 x 5.4 - 7.8 µm (Grgurinovic) or 9.5 - 12 (-13.5) x (6-) 6.5 - 8 µm (Bas) and are elongate to cylindric and amyloid.  Clamps are absent at bases of basidia.

Neither Bas nor Grgurinovic has ever seen the species fresh.  The specimen on which the current name is based was avoided as a type by Bas (1969) because too little was known of it (there are no collector's notes whatsoever); and the specimen is apparently the only one known of this entity.  It was collected in the state of South Australia.  No plants were reported in association with the mushroom.
