cap The cap of A. boudieri is about 40 - `10 mm wide, hemispherical to convex when young, becoming plano-convex with a slightly depressed center with age, white to whitish, sometimes becoming yellowish, dry, unpolished, appendiculate, with a nonsulcate margin.  The cap probably subviscid to shiny between remnants of volva at the margin.  The cap is at first completely covered with adnate, subtomentose-subfelted to pulverulent-subtomentose, white, volval layer, sometimes decorated with small, pustular warts; later, the covering layer more or less breaks up into rather vague, large, irregular, crust-like to small, rounded, wart-like subtomentose-subfelted patches.
gills The gills are rather crowded, subadnate to free, moderately broad, and white to cream or yellowish.  The short gills are rounded-truncate.
stem The stem is about 50 - 150 × 5 - 20 mm, cylindrical or attenuate upward, solid, white, with one to three vague circles of usually indistinct, flocculose-felted warts.
spores The spores measure 10.5 - 14 (-16.0) × (4.5-) 5.0 - 6.5 (-7.5) µm and are amyloid and elongate or elongate-obovoid to cylindical.  Clamps are present at bases of basidia.
discussion This species is known from the Mediterranean region.

See discussions under A. polypyramis (Berk. & M. A. Curtis) Sacc. and A. pulverulenta Beeli.  At first, Bas (1969) accepted the name A. baccata for this species; however, the type of the latter species is a plate that resembles both A. boudieri and A. gracilior Bas ex Bas & Honrubia (a taxon lacking clamps on its basidia and assignable to Bas' stirps Virgineoides).

Apparently, A. boudieri and A. gracilior are often confused in the field.  A study by Neville and Poumarat (1996) reveals that A. boudieri is uncommon and occurs mostly in the first half of the year, while A. gracilior is common and occurs in the second half of the year.  In my herbarium, all material of A. boudieri is from the period including March through May; and all material from A. gracilior is from the months including September through November.—R.
