Exidia truncated

Exidia compressed: photo and description

Compressed exidia is a poorly studied mushroom, which, perhaps, only avid mushroom pickers know about. What are these gifts of the forest, it is worth finding out before the start of the "quiet hunt".

What does Exidia look like

The mushroom resembles a closed shell with a barely noticeable stem 2-3 cm long. The fruit body is erect, rounded, leaf-shaped, compact, disc-shaped, or in the form of an inverted cone. As a rule, the surface of a young exidium is compressed smooth, but over time it becomes folded and wrinkled.

Color - from yellow and amber shades to red-brown, and when dry, the pulp begins to turn black. The edge of the fruiting body is wavy-wrinkled. It is characterized by an expressionless taste and smell.

Basidia are tetrasporous with a buckle at the base and long cylindrical sterigmas, reaching sizes of 10-13 × 7-10 microns. Spores 12-14 × 3-4 μm, thin-walled, hyaline, allantoid with a pronounced apex.

Is the mushroom edible or not

Mushrooms of this genus have several varieties, some of which are edible. However, this specimen belongs to the group of inedibles, but is not considered poisonous.

Where and how it grows

You can meet this species on dead deciduous wood that grows along rivers and lakes.

The variety is widespread throughout Russia, and the favorable time for their growth is from July to September. However, in some parts of the country with a mild climate, this specimen continues to grow continuously.

For example, in the southern region of Russia, where frosts reach a maximum of -10 degrees in winter, fungi do not die. And at above-zero temperatures, they continue to develop and form spores. In those regions where winters are more severe, for example, in the European part, exsidia winters successfully and begins to grow immediately after the thaw.

In dry weather, the fruit bodies dry out, acquiring a black tint, turning into hard thin crusts, the viability of which is several years in herbarium conditions. However, with heavy rain, the mushrooms return to their original form.

Doubles and their differences

There are several types of mushrooms that are considered twins of the Compressed Exidia:

1. Exidium glandular - resembles compressed in shape and color. Nevertheless, the glandular has a more saturated black color, and small warts can be seen on the surface of the fruiting body. This doppelgänger is believed to be an edible and delicious mushroom.
2. Truncated exidia - similar in color and shape. You can distinguish a double from a real one by the presence of a lower velvety surface and small warts on its fruiting body. They are classified as inedible.
3. Exidia blossoming - has a similar color and rounded flattened fruiting bodies. However, it will not be so difficult to distinguish a twin from a compressed exsidium, since most often it grows on a birch. This variety is never found on willow. It is an inedible species.
4. Leafy shiver - similar in shape and color to fruit bodies, but this species is quite rare and grows on stumps. Experts classify it as inedible and do not recommend using it for food.

Exidia blackening

Exidia nigricans (With.)

Description

Fruit body: 1-3 cm in diameter, black or black-brown, at first rounded, then fruiting bodies merge into one lumpy medullary mass, extending up to 20 cm, adherent to the substrate.The surface is shiny, smooth or wavy-wrinkled, covered with small dots. When dry, they become hard and turn into a black crust covering the substrate. After rains, they can swell again.

Flesh: dark, transparent, gelatinous.

Spore powder: white. The spores are elongated, 12-16 x 4-5.5 microns.

Taste: negligible. Smell: neutral.

It appears in spring in April-May and grows until late autumn under favorable conditions.

Similar species

Exidia spruce (Exidia pithya) - grows on conifers, fruit bodies are smooth. Some mycologists believe that spruce exsidia and blackening exsidia are one species.

Exidia ferruginous (Exidia glandulosa) - grows only on broad-leaved species (oak, beech, hazel). Fruit bodies never merge into a common mass. The spores of the glandular exidia are slightly larger.

Is the mushroom edible or not

The specimen is considered inedible, but it is not considered poisonous either. Due to the lack of smell and taste, it is not a valuable food product.

Where and how it grows

Exidia grows black on dry branches or trunks of deciduous trees, covering a large area. It can be found in the forests of Western Siberia. Fruiting begins in April and lasts until late autumn.

Doubles and their differences

Exidia compressed, like any representative of the mushroom kingdom, has its counterparts:

1. Spruce trembling. Grows on dried conifers. The cushion fruit body is formed by a dense gelatinous mass, black with an olive tint. The surface is smooth and shiny, hardens and forms a crust during dry periods. It can be found in all coniferous forests of Russia.
2. The trembling is glandular. It grows on dried wood of beech, oak, aspen and hazel. The fruit body has a jelly-like consistency; during mass growth, they never grow together. The shiny olive, brown or bluish surface hardens and becomes dull in dry weather. The pulp is thin, firm, without mushroom taste and smell. Considered conditionally edible. It can be eaten raw when preparing salads and dried when cooking soups.

Conclusion

Exidia blackening is a beautiful representative of the mushroom kingdom. The jelly-like pulp is colored shiny, black. Prefers to grow on dry trunks of deciduous trees. In Russia, the mushroom is considered inedible, but in China a variety of dishes are prepared from it.

Exidia

Exidia glandular Exidia compressed

Exidia is a widespread species of the large Auriculariaceae family; these mushrooms grow in Russian forests almost everywhere. They have a pulp similar to dense jelly and an indefinite shape of fruit chalk. They have a characteristic feature, they dry out in heat / drought, in cool rainy seasons they swell again and grow actively. Therefore, they become noticeable only in autumn and spring, although they can appear in cold, damp summers. In our region, two species are often found, both prefer alder-willow thickets, I have tasted (raw!) No taste at all!

Exidia glandular (Exidia glandulos)

Exidia glandular on birch

It is sometimes called glandular tremor. Actually, it does not look like mushrooms at all, fruiting bodies are born in the form of shapeless dense gelatinous tubercles densely adhered to wood. Growing up, as a rule, they merge into irregularly rounded or elongated blotches with clearly defined edges. The surface is glossy with numerous winding folds and peculiar rounded mini outgrowths (lat. Carrier glands).

Elastic flesh, odorless and absolutely tasteless. Colors of all shades of brown and black. Spores form over the entire surface of the fruiting bodies; therefore, drying mushrooms are often covered with a whitish spore powder. They grow on fallen trunks and thick branches of deciduous trees. Drying, they turn into a thin smoothed crust. Exidia glandular is edible and they write that it even has medicinal properties. Only eat raw!

Exidia compressed (Exidia recisa)

In Latin, "recisa" stands for abbreviation

Exidia compressed on aspen

Compressed exsidia mushrooms are compact, small (1 - 2.5 cm).Fruit bodies are rounded, wrinkled, with uneven edges and tiny, barely noticeable legs or a narrowed base. The outer surface is matt, the inner spore-forming is smooth and shiny. mobile pulp is translucent, thin, without any taste or smell. The color of the fruit bodies is brownish-yellow, orange-brown or reddish-brown, usually grows in small families, but usually does not form intergrowths. When dried, compressed significantly decreases in size, shrinks, becoming a dull dark brown color. Grows on decaying deciduous trees / branches, preferring willow trees. These nondescript woody mushrooms have hardly been studied, so their edibility is not known. Poisonous species are not described among exsidia, they are simply not edible due to their small size, unappetizing appearance and hard gelatinous pulp.
