Pycnoporellus alboluteus - Mushroom annual. In the shape of a rather irregular, mostly cushion, resupinate, more or less elongated. Reaching a length from 100 to 3000 mm and a width of 50 to 500 mm. Sometimes it spreads out - bent 4-40 x 30 - 50 x 10-50 mm, very poorly attached to the ground.

The hat is often formed by the outer walls of the tubes, therefore with irregularly porous surfaces, not brindled. Yellow-orange or brown-orange, then darkening. Shore usually lighter and irregularly roughly serrated.

Tubes 5 to 30 mm long. Usually the longest in the center of resupinates, with inter-flow barriers from 60 to 600 μ thick. The edges are usually brighter, at first dull, smooth and slightly ciliated, later ragged and deeply torn. Because of this, they eventually become spatulate or lamellar - spiky. In color, initially whitish, white-yellowish, yellowish, finally brown-orange, the inner walls of the tubes are covered with a whitish coating. They turn gradually from the root towards the blades.

Pores very large, 1 to 3 mm in diameter, irregular, angular, often oblong, sinuate or labyrinthaceous.

The pulp in its youth is juicy, soft, spongy and elastic, after drying it is light and fragile, in the dry state in the dry state paperwork. Thicknesses from 0.5 to 3 mm in the fruiting bodies of capens, and in the case of resupinates from 0.25 to 0.6 mm. In young sporocarps of the whitish, white-yellowish color, only the placenta has a light shade of orange, and the blades of the tubes are almost completely white. As it matures, the orange color becomes more intense and moves gradually through the inter-wall partitions towards the blades. After drying, the entire fruiting body is usually orange.

Occurrence: In forests on wood just above the ground, on the lower side of coniferous trunks, mainly spruce and pine.
