General description

The collection and consumption of this species is not prohibited by Russian legislation, as psilocybin has not been detected in the Verdigris Agaric. Consumption of the mushroom raw does not lead to hallucinations, but causes gastroenterological poisoning that is not life-threatening.

Habit

Fruiting body

Agaricoid (cap and stipe)

Hymenophore

Lamellate (gills present, including folded or rudimentary)

Mushroom cap

3–10 cm in diameter, initially conical, at maturity expanding to convex and convex-expanded with an umbo in the center. Surface slimy, sticky, non-hygrophanous; in young fruiting bodies blue-green, gradually fading unevenly, forming spots and smooth transitions between yellow-green, ochre, and blue hues.

Hymenophore: lamellate. Gills adnate or adnate with a tooth, with lamellulae, slightly swollen, initially light, pinkish-beige, at maturity creamy with a lilac tint, lilac-brown; gill edge finely serrated, fringed, contrastingly white.

Stem

10 × 0.4–2 cm, hollow, concolorous with the cap, with a distinct lighter ring; white with a bluish tint, sometimes brownish in the lower part; below the ring covered with scales, above it smooth or fibrous.

Flesh

Thin, soft in the cap, bluish; denser in the stipe, with greenish-blue shades.

Odor

Weak, herbaceous or slightly spicy-sharp.

Microscopy

Spore print light brown. Spores ellipsoid or slightly almond-shaped, smooth, with an indistinct germ pore.

Ecology and distribution

Litter saprotroph. Grows singly and in groups on more or less acidic, nutrient-rich soil, leaf litter, and decaying wood in forests of various types, in shrublands, along roadsides, in parks and gardens, on refuse heaps, sometimes among mosses at the edges of pastures and grazing lands.

Fruiting

August–October

Nutritional properties

Conditionally edible

An interesting and controversial mushroom both regarding edibility and psychoactivity. However, regarding the latter, it should be stated immediately that psychoactive properties are extremely weakly expressed, and an effect may appear only after consuming about 1 kg of raw mushroom. In Europe it is considered an edible species, though of low culinary value; in the USA it is generally regarded as poisonous. Some populations may contain meconic acid — one of the components of opium. In domestic mycological science, the Verdigris Agaric is considered conditionally edible, suitable for consumption after preliminary boiling. Before eating, it is also recommended to peel the skin from the cap.

Conservation status

Not listed in the Red Data Book of the Russian Federation or its regional Red Lists.

Similar species

Sky-blue Stropharia (Stropharia caerulea) grows outside forests, in parks, on pastures and clearings. It has a more blue hue. False-blue Stropharia (Stropharia pseudocyanea) is a meadow species, with a more slender build of fruiting bodies.

Notes

Да, это верное наблюдение. Концентрация действующих веществ в грибах действительно непостоянна и зависит от множества факторов: состава почвы, климатических условий, стадии развития плодового тела, времени сбора и даже способа приготовления.

Поэтому один и тот же вид в разных условиях может проявлять себя по-разному — от полностью съедобного до вызывающего лёгкое отравление или, в редких случаях, более серьёзные реакции. Именно по этой причине многие грибы классифицируются как «условно-съедобные»: они требуют обязательной предварительной обработки (отваривания, вымачивания, ферментации) и индивидуального подхода к оценке рисков.

Если ты собираешь грибы для еды, важно не только точно определять вид, но и учитывать местную специфику: где растёт гриб, в какой экосистеме, не загрязнена ли почва тяжёлыми металлами или другими токсинами. Даже съедобные виды могут накапливать вредные вещества из окружающей среды.

Так что осторожность, умеренность и знание местных условий — ключевые правила безопасного грибного сбора.
