Japanese Technical description (t.b.d.)

BRIEF DESCRIPTION: Basidiocarps medium-sized to large. Pileus 70 - 150 (-200) mm wide, convex to applanate, sometimes concave, white, covered with white, conical to pyramid volval remnants 1 - 3 mm high and wide; the cap margin is smooth and appendiculate; and the context is white and unchanging.

The gills are free to subfree and white to cream; the short gills are attenuate.

The stipe is 100 - 200 x 15 - 30 mm, subcylindric or aslightly attenuate upwards, white, covered with white floccose squamules; the context is white; the stipe's basal bulb is 30 - 40 mm wide, ventricose, ovoid to subglobose, with its upper part covered with white, verrucose to granular volval remnants. The annulus is white; its upper surface bears fine, radial striations; and its lower surface, verrucose to conical warts. The annulus is often broken during expansion of the cap.

The spores measure (7.0-) 8.0 - 10.0 (-11.5) x (5.5-) 6.0 - 7.5 (-8.5) ?m and are broadly ellipsoid to ellipsoid and amyloid. Clamps are common at bases of basidia.

The species was originally described from Japan. Amanita virgineoides is also known from China and South Korea. ZLY's photograph depicts a gathering of this species for sale in a market

Bas (1969) defined his stirps Virgineoides based on the present species. This stirps also includes A. miculifera Bas & Hatan. and A. gracilior Bas ex Bas & Honrubia. -- Zhu L. Yang and R. E. Tulloss

Habitat solitary to a few together in hardwood forests, mixed hardwood-conifer (Quercus & Pinus) forests, summer-fall. Distribution: Japan.
Pileus 90-200 mm across, spherical when young, then convex to plain, margin with debris of annulus, surface covered with white powder, and covered with pyramidal warts which tend to be separabe.
Lamellae white, later cremoricolor.
Stipe 120-220 x 15-25 mm, cylindrical, bottom enlarged toward the base which is clavate, surface white with warts; annulus is wiped off when the pileus opens.


False virgin's lepidella (Amanita virgineoides) belongs to Amanitaceae (Amanita family). It is a fungi that is distributed to Japan, southern Korean Peninsula and China. This fungi occurs in forest floors of Japanese red pine, oak or quercus from summer to fall. The pileus is white and covered with numerous conical volval remnants. The stipe is also white, swollen clavate at the base and covered with conical volval remnants. This fungi is extremely-poisonous.

散歩していたら,コナラとサクラなどの混じる落葉樹の林で白く大きなキノコを見つけた。成長途中のシロオニタケのようだ。まだまだ大きくなる。

シロオニタケ(Amanita virgineoides Bas)は,テングタケ科テングタケ属に属し,日本と韓国に分布するキノコということだ。

見るからに毒キノコという装いをしている。ところが,不思議なことにも,このキノコが毒キノコかどうかはよく分かっていない。おそらく,あまりにも毒キノコらしい姿をしているので,誰も食べたことがないのだろう。(笑)

私は,このキノコをこれまで何度も見た。大きなものは傘の直径が20センチ以上になる。この写真のものは,傘の直径が12センチ前後だったので,まだまだ大きくなる途中のものだろうと思う。

「オニタケ」という名をもらっているだけあって,傘の表面にトゲのような突起がたくさんある。造形として見た場合,非常に興味深いキノコだと

Poi ti posto le immagini.

-6565 a tutti
Molto sembra a metà strada tra A. echinocephala e la A. gracilior.

Chers amis, Merci de vos réactions très intéressantes.
Je connaissais bien echinocephala (aspera ss. auct.) de France.
Les ressemblances macroscopiques sont frappantes !

Je pense que ces taxa sont très proches, au moins la section...
Je vais chercher encore mes herbiers et notes... Merci
