    1. Amanita labordei - from plate in orig. description, basidiome on left too dark on left half

    • intro

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

    cap

    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.

    gills

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

    stem

    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.

    spores

    The spores of A. labordei measure 9 - 12.5 × 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.

    discussion

    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
