| Amanita fulvopulverulenta Beeli "Fulvous-powdered Amidella" :: Technical description (t.b.d.) BRIEF DESCRIPTION: The following description is based on Beeli (1935). The cap of Amanita fulvopulverulenta is 90 - 100 mm wide, flattened-convex, fleshy, with a slightly prominent umbo, with a slightly striate margin. The cap is pale pinkish brown covered with brownish-red, powdery remains of the volva. The gills are free, slightly yellowish, and somewhat rounded at the end near the stem. Its stem is 120 - 170 × 10 - 20 mm, solid, and cylindric. It may appear slightly bulbous at the base because of the robust volval sac. The surface is fibrillose to glabrous, white or slightly tinted red. The flesh is whitish but turns pink when cut. The stem is easily separated from the cap. Beeli measured spores as 7 - 8 × 4 µm and are amyloid and elongate to cylindric. Gilbert's spore measurements are 7.5 - 11.3 × 3.7 - 5.0 µm. The present species was originally described from the Republic of Congo in dry forests. E.-J. Gilbert's comment that this species is very similar to A. goossensiae Beeli is not borne out by his own spore data (1941). The pigments, spore shape, flesh changing to
pink when cut, membranous volva that has a powdery inner-layer, and
narrow spores are all good indicators that this species belongs in
section Amidella [typified by the American species A.
volvata
(Peck) Lloyd]; however Madame Goossens painting shows a
section of a button with a very distinct bulbous base. In the
macroscopically similar A. goossensiae Beeli and A.
fulvosquamulosa Beeli, Madame Goossens
carefully distinguished the flesh of the totally elongating stem from
the strongly thickened volval sac. That she failed to do so in the
case of the present species is difficult to interpret since I have
never revised dried material. If Madame Goossens painting is correct,
then A. fulvopulverulenta would be an exception to stipe
development in section Amidella. Return to Section Amidella page. Last changed 15 August 2005. |
