Fruit bodies are annual, small (1.5 to 5 cm across), semicircular or shell-shaped, usually widely attached, usually arranged in more or less numerous imbricate groups. On horizontal substrates – for example, on the surface of stumps – they can grow in the form of rosettes. The edge of young fruiting bodies is rounded, in mature ones it is sharp, slightly bent down. There is a tubercle at the base of the cap.

The upper surface is matt to velvety and softly hairy, with more or less pronounced concentric bands in grey-ocher-brown tones. The stripes are slightly blurred. With pronounced striping, the base of the cap is often dark. In general, despite the modest color scheme, ocher trametes is colored very diversely. Some specimens can even boast of orange tones. Hairiness can also be zonal, with alternating pubescent and non-pubescent stripes, as well as stripes with vertical and appressed pile.

The lower surface of young fruiting bodies is milky white to creamy, becoming brownish when dry. When damaged, the color practically does not change. The pores are rounded, 1-4 mm deep, 3-4 pores per millimeter.

Spores are curved-cylindrical (allantoid or sausage-shaped), smooth, 5.5-8 x 2.3-3.1 µm, non-amyloid. Spore powder is white.

The fabric is white, dense, leathery or corky. The smell is described by different authors in different ways: from inexpressive to reminiscent of the smell of freshly caught fish. The taste is unexpressed.

Ochryan trametes grows on dead wood and hardwood, causing white rot. The economic activity of a person does not interfere with him at all, on the contrary, but since it does not grow on living wood, it does not cause any significant damage, for example, to forestry. This is a fairly common species in the Northern Hemisphere. Old fruiting bodies decompose slowly, so ocher trametes can be found throughout the year, although it looks most spectacular in autumn, during the period of active sporulation.

The mushroom is inedible due to its rigidity.

The multicolored trametes (Trametes versicolor) is distinguished by its incredibly varied coloration and darker tones, although its light and brown forms can be easily confused with the ocher trametes. In this case, you should pay attention to the tubercle at the base of the cap (it is absent in the trametes multicolor), the size of the pores (they are slightly smaller in the trametes multicolor) and the size of the spores (they are much smaller in the trametes multicolor).

Stiff-haired trametes (Тrametes hirsutum) is distinguished by grayish or olive tones of the upper surface (which in old fruiting bodies is often overgrown with epiphytic algae) and hard pubescence up to bristly. In addition, rough-haired trametes grows not only on dead wood, but also on living trees.

Fluffy trametes (Trametes pubescens) have white or yellowish fruiting bodies, thin-walled, angular pores, and the fungus itself is very short-lived – it is quickly destroyed by insects.
