Ocher Trametes (Trametes ochracea)

Description

Fruit bodies are annual, small in size (from 1.5 to 5 cm in diameter), semicircular or shell-shaped, usually widely attached, usually located in more or less numerous tiled groups. On horizontal substrates – for example, on the surface of stumps – they can grow in rosettes. The edge of young fruit bodies is rounded, in mature ones it is sharp, slightly curved downwards. There is a tubercle at the base of the cap.

The upper surface is matt to velvety and softly pubescent, with more or less pronounced concentric stripes in a gray-ocher-brown range. The stripes are slightly blurred. With pronounced banding, the base of the cap is often dark. In general, despite the modest color range, ocher trametes are very diversely colored. Some examples even boast orange tones. The pubescence can also be zonal, with alternating pubescent and non-pubescent stripes, as well as stripes with vertical and pressed pile.

The lower surface of young fruiting bodies is from milky white to creamy; when dry it becomes brownish. 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 expressionless to reminiscent of the smell of freshly caught fish. The taste is unexpressed.

Ecology and distribution

Ochreous Trametes grows on dry and pale deciduous trees, causing white rot. Human economic activity does not interfere with it, 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 fruit bodies decompose slowly, so ocher tramesto can be found throughout the year, although it looks most spectacular in autumn, during the period of active sporulation.

Edibility

The mushroom is inedible due to its toughness.

Similar species

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

The hard-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, hard-haired trametus grows not only on dead wood, but also on living trees.

Trametes pubescens have white or yellowish fruit bodies, thin-walled, angular pores, and the mushroom itself is very short-lived – it is quickly destroyed by insects.
