Row white-brown Tricholoma albobrunneum

Description of the mushroom

The hat is 4-10 cm in diameter, in youth it is hemispherical, with a curled edge, then from convexly outstretched to flat, with a smoothed tubercle, radially fibrous-striped, not always pronounced. The peel is fibrous, smooth, can crack, slightly, forming the appearance of scales, especially in the center of the cap, which is often finely scaly, slightly slimy, sticky in wet weather. The edges of the cap are even, with age they can become wavy-curved, with infrequent, wide bends. The color of the cap is brown, chestnut-brown, maybe with a reddish tint, in youth with dark veins, more uniform with age, lighter towards the edges, up to almost white, darker in the center. There are also lighter specimens.

The pulp is white, under the skin with a reddish-brown tint, dense, well developed. Without any special smell, not bitter (according to some sources, flour smell and taste, I do not understand what this means – author's note).

The plates are frequent, adherent with a tooth. The color of the plates is white, then with small reddish-brown spots, which gives them the appearance of a reddish color. The edge of the plates is often torn.

Spore powder is white. Spores are ellipsoidal, colorless, smooth, 4-6×3-4 μm.

The leg is 3-7 cm high (up to 10), with a diameter of 0.7-1.5 cm (up to 2), cylindrical, in young mushrooms it is more often expanded towards the base, with age it can become narrowed towards the base, solid, with age, rarely, it can be hollow in lower part. Smooth from above, longitudinally fibrous to the bottom, outer fibers can be torn, creating the appearance of scales. The color of the leg is from white, at the point of attachment of the plates, to brown, brown, reddish-brown, longitudinally fibrous. The transition from white to brown can be either sharp, which is more common, or smooth, the brown part is not necessarily very pronounced, the stem can be almost completely white, and, conversely, slight brownishness can reach the very plates.

Habitat

White-brown ryadovka grows from August to October, it is also seen in November, mainly in conifers (especially dry pine), less often in mixed (with a predominance of pine) forests. Forms mycorrhiza with pine. Grows in groups, often large (singly – rarely), often in regular rows. It has a very wide distribution area, it is found practically throughout the territory of Eurasia, where there are coniferous forests.

Similar species:

  • Scaly row (Tricholoma imbricatum). It differs from the rowing in the white-brown significant scaly of the cap, the absence of mucus in wet weather, and the dullness of the cap. If the white-brown ryadovka has a place to have insignificant scaling in the center, which comes with age, then the scaly row stands out precisely by the dullness and scaly of most of the cap. In some cases, they can be distinguished only by microscopic features. For culinary qualities it is identical to the white-brown ryadovka
  • Row yellow-brown (Tricholoma fulvum). Differs in the yellow color of the pulp, yellow, or yellow-brown color of the plates. Does not occur in pine forests.
  • Broken row (Tricholoma batschii). It is distinguished by the presence of a thin film ring, with a feeling of its slimy, under the cap, in the place where the brown part of the leg turns into white, as well as a bitter taste. In terms of culinary qualities, it is identical to the white-brown ryadovka.
  • Row golden (Tricholoma aurantium). Differs in a bright orange or golden-orange color, small scale of the entire, or almost all, area of ​​the cap, and the lower part of the leg.
  • Spotted row (Tricholoma pessundatum). This weakly venomous mushroom is characterized by the presence of dark spots on the cap, located in circles, or short, rather wide dark stripes, located periodically, radially along the edge of the cap, along its entire circumference, finely grooved frequent waviness of the folded edge of the cap (in white-brown waviness, if any, sometimes infrequent, several bends), the absence of a tubercle in age fungi, a strongly pronounced asymmetric curvature of the cap of old mushrooms, and a bitter flesh. She does not have a sharp color transition from the white part of the leg to brown. Grows either singly or in small groups, rarely found. In some cases, it can be distinguished only by microscopic features. To reject such mushrooms, one should pay attention to mushrooms growing singly or in a small group that do not have a sharp contrasting color transition on the stem, and have at least one of the first three described differences (spots, stripes, small and frequent grooves), and, also, in suspicious cases, check for bitterness.
  • Poplar row (Tricholoma populinum). Differs in the place of growth, does not grow in pine forests. In forests mixed with pine, aspen, oaks, poplars, or at the borders of the growth of conifers with these trees, you can find both, poplar, usually fleshy and large, with lighter shades, however, often they can only be distinguished by micro signs, if, of course, there is a purpose to distinguish them, since mushrooms are equivalent in their culinary properties.

Edibility

White-brown ryadovka belongs to conditionally edible mushrooms, it is used after boiling for 15 minutes, universal use. However, in some sources, especially foreign ones, it is ranked among inedible mushrooms, and in some – as edible, without the prefix 'conditionally'.
