Technical description not yet available.

BRIEF DESCRIPTION: The following is largely derived from the original description of A. labordei (1942-43?).

The cap of A. labordei is yellow (most intense of the center, less so at the margin, and often greater than 90 mm wide; it is subglobose at first, then convex, eventually expanding to plano-convex with a depressed center. The cap's margin is not striate and markedly extends beyond the ends of the lamellae. The volva is present on the cap as a farinose layer and large, rather dark, brownish warts.

The gills are a very pale citrin yellow in side view and moderately distant.

The stem (probably including the bulbous base) is about 100 mm long, with a turnip-shaped to narrowly spindle-shaped bulb that is up to 35 mm wide. The stem is covered with a farinose layer and bears a distinct annulus. The volval remnants on the basal bulb may be distinctly limbate in the button stage, but are soon lost.

The spores of A. labordei measure 9 - 12.5 x 5.5 - 7 um and are white in mass, amyloid, and ellipsoid. There is no report of the presence or absence of clamps on the bases of basidia.

It is not yet clear to me whether Amanita section Lepidella is the correct section for classification of this species. Moreover, the yellow tints in the illustration (above) suggest the presence of the "yellowing disease" seen in a number of species of sect. Lepidella from around the world. See the discussions on the species pages for A. alboflavescens Hongo and A. subsolitaria (Murrill) Murrill (=A. crassifolia Bas nom. prov.). I have also received African material from David Arora with color photographs showing that the material stained yellow when cut in its fresh condition.

The poorly known species was described originally from a Eucalyptus plantation in the Malagasay Republic (then Madagascar). To my knowledge, A. labordei has not been reported since the original publication. -- R. E. Tulloss
