english name "Large-Spored Woolly Lepidella"
intro The following is based on the original description (Bas 1969).
cap The cap of Amanita lanosula is about 60 - 100 mm wide, more or less plano-convex, perhaps with a slight, central depression, and with a vague umbo.  The appendiculate margin is not (or vaguely) striate.  At first, the cap is entirely covered with a dark brown, floccose-warty volva; in age this tends to break up into dark brown, small warts at the center and then completely disappears exposing a somewhat paler brown(?), shiny cap.
gills The gills are crowded, free, moderately broad to rather narrow, and white(?).  The short gills are obliquely truncate to attenuate.
stem The stem is about 120 - 200 × 5 - 15 mm, exannulate, probably brown or brownish, fibrillose, with scattered, very small, dark brown, scale-like warts at the base of the stem and on the upper part of the bulb, which is slenderly fusiform to elongate napiform.
spores The spores measure 8 - 10 × 5.5 - 6.5 µm and are amyloid and ellipsoid to elongate.  Clamps are present at bases of basidia.
discussion This species was described from what is now the Democratic Republic of Congo.  It was reportedly associated with Gilbertiodendron (=Macrolobium) dewevrei (De Wildem.) Léon.

The present species differs from A. lanosa Beeli by having differently shaped spores, a different pattern of gelatinization of the cap surface, a thinner annulus with less material left on the upper stem, a more slender bulb, and some volval scales on the base of the stipe above the bulb.

Bas included the present species in his stirps Chlorinosma.  See A. chlorinosma (Peck) Lloyd.—R. E. Tulloss
