Species epithet Tricholoma stiparophyllum (N. Lund) P. Karst., Meddn Soc. Fauna Flora fenn. 5: 42 (1879) comes from a combination of the words stipo, which means "to gather tightly, to crowd," and phyllus (referring to leaves, in the mycological sense to plates). Hence, the Russian-language epithet is often-plate.
The hat is 4-14 cm in diameter, convex or bell-shaped in youth, flat-convex or prostrate at age, it can be with a rather low tubercle, smooth or slightly velvety, in some cases it can crack. The edge of the cap is bent for a long time, then straight, in rare cases, in old age, turned up, often wavy, often ribbed. The hat is painted in light, white, whitish, fawn, creamy colors. The hat in the center is often darker fawn, and dark spots and / or streaks of fawn or ocher shades are also often observed.
The flesh is firm, from white to fawn.
The smell is pronounced, unpleasant, in various sources described as chemical, like the smell of coal (coke oven) gas, the smell of stale food waste or the smell of dust. The latter seems to me the most accurate hit.
The taste is unpleasant, with a musty or rancid flour aftertaste, slightly spicy.
The plates are from adherent to notched-adherent, of medium width, medium-frequent, white or cream, with age or on lesions with brown spots.
Spore powder is white.
Hyaline spores in water and KOH, smooth, mostly ellipsoidal, 4.3-8.0 x 3.1-5.6 μm, Q 1.1-1.9, Qe 1.35-1.55
The leg is 5-12 cm long, 8-25 mm in diameter, white, pale yellowish, in the lower part often with yellow-brown spots or stains, cylindrical or slightly widened below, often rooting, covered in this place with a white felt mycelium, in in other places it is smooth, or with a slight frost-like bloom, often fine-scaled in the lower part.
The lamellar row grows from August to November, is associated with birch, prefers sandy and peaty soils, but it also occurs on other types of soils, is widespread and very wide, often forms rather large clusters in the form of circles, arcs, straight sections, etc.
- Row white (Tricholoma album). We can say a twin species. It differs, first of all, in living together with an oak. The edge of the cap in this species is not ribbed, and, on average, the white row has fruit bodies of a neat and even shape. The scent of this species contains sweetish honey notes against an overall less opposite background. However, if the mushroom is found where there is both a birch and an oak nearby, it is often extremely difficult to make a decision about the type, and it is not always possible.
- Row fetid (Tricholoma lascivum). This species is also often confused with a lamellar row, and even more so with a white one. The species grows with a beech on soft humus (mule) soils, has a strong bitter and pungent aftertaste, and has a gray-yellow color that is not typical for the species in question.
- Stinky row (Tricholoma inamoenum). It has rare plates, fruiting bodies of a noticeably smaller and puny species, inhabits spruce and fir.
- Rows of Tricholoma sulphurescens, Tricholoma boreosulphurescens. They are distinguished by yellowing of the fruit bodies at the places of touch, despite the fact that they smell just as disgusting. If the first of them grows together with beech or oak, then the second, like the lamellar one, is associated with birch.
- Humpbacked row (Tricholoma umbonatum). It has a pronounced radial-fibrous structure of the cap, especially in the center, has olive or greenish tints in the fibrous part, its smell is weak or floury.
- The row is whitish (Tricholoma albidum). This species has a not very clear status, like, for today, it is a subspecies of the silver-gray row - Trichioloma argyraceum var. albidum. It differs in the radial texture of the cap, similar to a pigeon ridge or with silvery rows, it is distinguished by yellowing at the places of contact or yellow spots for no apparent reason, and a mild flour smell.
- Pigeon row (Tricholoma columbetta). It has a pronounced radial-fibrous silky-shiny structure of the cap, by which it immediately differs. Its smell is weak or mealy, pleasant.
The lamellar row is considered inedible because of its unpleasant smell and taste.
