Sandy geopore: edibility, what it looks like, where it grows, how to distinguish it, photo

Chestnuts are edible and inedible how to distinguish

Edible chestnut and horse chestnut are completely different trees, despite the similarity in the name. The first belongs to the beech family, and the second belongs to the sapindaceae. Outwardly, the trees are not at all similar, so it is not difficult to distinguish them.

Edible species

It will be useful for everyone to know what chestnuts can be eaten. There are several types of food:

1. Gorodchaty (Japanese). The largest-fruited variety. Grows up to 15 meters. Nuts up to 6 cm in diameter and up to 80 gr. in the mass.
2. Sowing. Reaches 35 meters. Prefers a humid and warm subtropical climate. Propagated by seeds. It features a powerful root system that holds the crown well.
3. American (notched). Frost-resistant variety, easily tolerates prolonged cold weather down to -30⁰С.
4. Chinese (softest). The fruits are distinguished by excellent taste and are widely consumed in food. Wood is in demand in industrial production. The plant is afraid of drought, requires frequent watering.
5. Stunted. A tree up to 15 meters high. Refers to decorative forms.
6. Australian. An evergreen tree reaching a height of 15-30 meters.
7. Shogyu. Resistant to pathogenic fungi affecting chestnuts.
8. Henry. Distributed in the western and central regions of China. Reaches a height of 25-30 meters.

At the time of ripening, the maximum amount of nutrients is concentrated in the fruits of the edible chestnut. Once the chestnuts are completely brown, they are harvested and harvested for the winter. They are eaten ready-made and raw.

Geopor Cooper (Red Data Book of Crimea)

(hairy truffle,
pine truffle)
 
Geopora cooperi Harkn.
 
Taxonomic position
The order is special (Pezizales).
Family Pyronemataceae.
 
Conservation status
A rare species (3). 

Features of morphology

Fruit bodies are lumpy-rounded, divided into lobes by more or less deep hollows (resemble in shape brain), 2–4 (5) cm in diameter. The surface is yellow-brown, chestnut-brown, slightly warty, covered with frequent brown hairs. Despite its unofficial names, Cooper's geopore is not related to true truffles, they are united only by the underground way of existence of fruit chalk. The main difference from real truffles is the structure of the fruit body on the cut: the “flesh” of the Cooper's geopore is not marble-like, but labyrinth-like, with winding narrow cavities, with alternating whitish (bearing spores) and brown (wrapped inside the integument of the fruit body) “convolutions”.

Features of biology

Symbiotroph, forms mycorrhiza with pines. Grows in pine forests and pine forest culture. Fruit bodies are underground / semi-underground, usually found singly or in groups (nests) in the surface layer of the soil or under fallen needles near pine trees. Despite its wide distribution in the Northern Hemisphere, finds of the species are rare everywhere. October November.

Security measures

Protected in the Karadag nature reserve. It is necessary to identify new locations and control the state of populations.
