Amianthin cystoderm (Cystoderma amianthinum), also called spinous cystoderm, asbestos and amianthin umbrella, is a lamellar fungus. Occurring subspecies:
- album - white hat variety;
- olivaceum - with olive color, found in Siberia;
- rugosoreticulatum - with radial lines radiating from the center.
The species was described for the first time at the end of the 18th century, and the modern name was consolidated by the Swiss V. Fayod at the end of the 19th century. Belongs to the extensive Champignon family.
What does amiant cystoderm look like?
The Amianthus Umbrella looks not too impressive, it can be mistaken for another toadstool. The fragile small body of the cystoderm has a rich color, from light sandy to bright red, like a well-baked cookie. The cap is initially round-spherical, then straightens, leaving a noticeable bulge in the central part. The fringed edge may curl inward or outward, or be straightened. The flesh of the body is tender, easily squeezed, light, with an unpleasant, moldy smell.
Description of the hat
The cap of the amiant cystoderm is rounded-conical when it appears. With maturation, the body opens, turning into an open umbrella with a convex tubercle at the junction with the leg, and a fluffy edge bent inward. The diameter can be up to 6 cm. The surface is dry, without mucus, rough due to small flake grains. The color ranges from sandy yellow to bright orange. The plates are thin, often arranged. At first pure white, then the color darkens to a creamy yellow. The spores that mature on the surface are pure white in color.
Leg description
The legs of the cystoderm are filled at the beginning of the cycle; as they grow, the middle becomes hollow. Long and disproportionately thin, they reach 2-7 cm in length with a diameter of 0.3 to 0.8 cm. The surface is dry, covered with large brownish scales in the lower part. The pale yellow rings that remain from the bedspread disappear with growth. The color is almost white at the base, yellowish-coffee in the middle and deep brown at the ground.
Is the mushroom edible or not
Cystoderm is not poisonous. Amianthus umbrella belongs to conditionally edible mushrooms due to its low nutritional value, watery pulp and unpleasant aftertaste. The hats can be used for preparing main courses, salting and pickling after boiling for a quarter of an hour. Legs have no culinary value.
Where and how it grows
Cystoderm grows in small groups or alone in a temperate zone. Of all the varieties, it is the amaranth umbrella that is most widespread in Russia. It appears from the beginning of August and continues to grow until the end of September-mid-November, until frost occurs. Loves mixed and coniferous forests, next to young trees. It climbs into moss and soft coniferous litter. Loves the neighborhood of ferns and lingonberry bushes.Occasionally found in abandoned parks and in meadows with herbs.
Doubles and their differences
Umbrella amiant in structure and color is similar to some poisonous varieties of mushrooms. It can be confused with representatives of such genera:
- Cobwebs.
- Lepiot.
To distinguish them, you should consider the cap, leg and color of the plates.
Conclusion
Amianthus cystoderm grows in the temperate latitudes of the Northern Hemisphere. The season falls at the end of summer and all autumn until the first frost. It can be eaten, although they are reluctant to take the amianthus umbrella because of the specific taste. The collected specimens should be carefully examined so as not to be confused with similar poisonous mushrooms.
