The float is gray, the form is white, as the name suggests, is the albino form of the gray float – Amanita vaginata. The main features, respectively, are very close to the main form, the main difference is the color.
Like all floats, the young fungus develops under the protection of a common blanket, which, when bursting, remains at the base of the leg in the form of a small pouch – a volva.
Hat: 5-10 centimeters, under favorable conditions – up to 15 cm. Ovate, then bell-shaped, later prostrate, with a thin ribbed edge. White, sometimes off-white, no other shades, only white. Pieces of the common blanket may remain on the skin.
Plates: white, thick, wide, loose.
Spore powder: white. Spores: 10-12 microns, round, smooth.
Leg: 8-15, sometimes up to 20 centimeters high and up to 2 cm in diameter. White. Central, cylindrical, even, smooth, at the base it can be slightly widened and pubescent or covered with thin white scales. Fibrous, hollow.
Ring: absent, completely, even in young specimens, there are no traces of the ring.
Volvo: loose, large, white inside and out, usually well visible, although buried in the ground.
Flesh: thin, brittle, brittle, white or whitish. The color does not change at the cut and break.
Smell: not expressed or weak mushroom, without unpleasant shades. Taste: no special taste, mild, sometimes described as weak mushroom, without bitterness and unpleasant associations.
The mushroom is considered edible, with low nutritional quality (the flesh is thin, there is no taste). Can be eaten after a single short boil, suitable for frying, can be salted and pickled.
Season and distribution
White float grows from mid-summer (June) to mid-autumn, September-October, with warm autumn – until November, in deciduous and mixed forests, on fertile soils. Forms mycorrhiza with birch. It is not often found, it is noted throughout Europe, more in the northern regions, including Ukraine, Belarus, the central and northern European part of the Russian Federation.
The float is gray, the form is white (albino) similar to the albino forms of other types of floats, and it is not possible to distinguish them 'by eye'. Although here it is necessary to clarify that the albino forms of other floats are extremely rare and practically not described. Among similar species, it should be noted: Snow-white float (Amanita nivalis) – contrary to the name, this species is not at all snow-white, the cap in the center is grayish, brownish or with a light ocher tint. Amanita phalloides in its light form Spring fly agaric (Amanita verna) Smelly fly agaric (Amanita virosa) Of course, these (and other light) fly agarics differ from floats by the presence of a ring. But! In adult mushrooms, the ring may already be destroyed. And at the 'embryo' stage, while the mushroom has not yet completely crawled out of the common bedspread (egg), you need to know where to look to determine the presence or absence of a private bedspread. Amanita muscaria is generally larger, 'fleshy', but this is a very unreliable sign, since it strongly depends on the weather and growth conditions of a particular fungus. Recommendations: I want to say something like 'don't pack white floats for food', but who will listen? Therefore, let's say this: do not pick up mushrooms thrown by someone, even if they are very similar to a white (and snow-white) float, since you cannot determine with certainty whether the notorious ring on the leg was there. Do not harvest Amish in the 'egg' stage, even if these buds are found next to a precise, undeniable float.
Notes Mikhail Vishnevsky notes that the fresh fruit bodies of the white float contain betaine, and in quantities exceeding the content of this substance in the porcini mushroom. In my opinion, the medicinal properties of betaine are greatly exaggerated. It is used as a food supplement, as a means for correcting liver function, as a hepatoprotective and metabolic agent. Attempts have been made to use betaine as a treatment for obesity, but there is no serious scientific evidence on the effect of betaine on overweight reduction. Conclusions: if you, dear reader, are going to use the white float 'as medicine' – leave this venture.
