Rowhead Gulden (Tricholoma guldeniae)

:

• Tricholoma guldenii

The species is named after the Norwegian mycologist Gro Gulden (Gro Sissel Gulden). Indicated in synonyms “Tricholoma guldenii” – an erroneous name (incorrect ending), is found in some sources.

head 4-8 (10) cm in diameter, conical in youth, bell-shaped, prostrate in age, often with a tubercle, dry, sticky in wet weather. The edge of the cap is first bent, then smooth or even wrapped up. The color of the cap is a radial dark gray, dark olive gray, in some places almost black fibrousness on a light background, which may have yellow, olive and greenish tints.

Pulp whitish, grayish, yellowish-greenish; in deep lesions, over time, often markedly grey. The smell is weak floury, the taste is floury, soft.

Records adnate with a notch or tooth, rather wide and not frequent, whitish, grayish, yellowish-greenish and even slightly pale shades.

After frosts, I met individuals in which the plates were partially creamy-pinkish. With age, grayness or paleness noticeably increases, there may be yellowness, especially when it dries, and especially along the edge of the cap, but the colder the weather, the less noticeable all this, especially grayness.

In places of damage, they usually have a gray border. Also, the gray bordering of the plates also appears with age, but is not observed in all populations, and even in one population, not every year.

spore powder white.

Споры hyaline in water and KOH, smooth, very diverse, both in size and shape, in one screening there are both almost spherical and ellipsoidal, according to [1] 6.4-11.1 x 5.1-8.3 µm, average values ​​8.0-9.2 x 6.0-7.3 µm, Q = 1.0-1.7, Qav 1.19-1.41. My own measurement on 4 mushroom samples gave (6.10) 7.37 – 8.75 (9.33) × (4.72) 5.27 – 6.71 (7.02) µm; Q = (1.08) 1.18 – 1.45 (1.67) ; N = 194; Me = 8.00 × 6.07 µm; Qe = 1.32;

Leg 4-10 cm long, 8-15 mm in diameter, white, whitish, often with yellow-greenish hues, uneven, spots. Mostly conical, tapering towards the base, but in juveniles it is often widened in the lower third. There are specimens both with a completely smooth leg, and with a pronounced fibrous-scaly, as well as with light scales, and with dark gray ones, while in the same population they can be with legs that are different in texture and appearance.

Row Gulden grows from the second half of September to November. According to [1], it lives in forests with the presence of spruce, however, also, findings have been seen in mixed forests with pine, oak, birch, poplar/aspen and hazel. But there is no confirmation that this species forms mycorrhiza with these trees. In my case, mushrooms were found in a mixed forest with spruce, birch, aspen, hazel, mountain ash. Some of the finds were under the fir trees, but one circle was clearly around a young hazel bush, but there was also a spruce about three meters away. In all my cases, it grew near the habitats of the deciduous row – Tricholoma frondosae, literally mixed in places.

• Row gray (Tricholoma portentosum). A very similar look. However, it is associated with pines and grows in mosses on sandy soil, therefore it practically does not intersect in biotope with Gulden rows, which usually grows on loamy or calcareous soils. A distinctive feature of the species are light plates, possibly with yellowish and greenish tones, but without gray tones and without gray edging. Although after frost, gray tones in the plates may appear in this species. Another important difference is the noticeably smaller spores.
• Row dirty yellow (Tricholoma luridum). Outwardly, it is also very similar, even more similar than the gray row. Differs in darker fawn-gray tones in plates. Serious confusion is associated with this species in various sources, since in the Scandinavian countries it was under this name that the Gulden row was listed before Morten Christensen described it in 2009. For example, this is how it is described in [2], moreover, in collaboration with M.Christensen, who later separated it. The true T.luridum has been found so far only in the mountainous part of central and southern Europe, with only separate mentions of it south of the Alps, in mixed forests with the presence of beech, spruce and fir on calcareous soils [1]. However, not enough time has passed to reliably state about its limited habitat. The spores of this row are on average larger than those of T. guldeniae and have a smaller variation in size.
• Row pointed (Tricholoma virgatum). This inedible, slightly poisonous row, also associated, including with spruce, with some interference can be attributed to similar species with the Gulden row. It is distinguished by a pronounced sharp tubercle on the cap, a brilliant silky gray color, without yellow and green hues, and a bitter, up to spicy, taste. Also, her hat is characterized by slight scalyness, which does not occur in the Gulden row.
• Row dark (Tricholoma sciodes). This inedible row is very close to the previous similar species, pointed row. It has the same distinguishing features, but the tubercle may not be as pointed, and its color is darker. Its taste at first seems mild, while unpleasant, but then a clear, first bitter, and then spicy aftertaste appears. It forms mycorrhiza with beech, so the chances of finding it near the Gulden row are minimal.

Row Gulden is a conditionally edible mushroom. In my opinion, in terms of culinary qualities, it is no different from gray row (serushka) and is very tasty in any form, especially in pickling and marinade, after preliminary boiling.
