Felt stereum (Stereum subtomentosum)
Description Fruit bodies are annual, 1-2 millimeters thick, shell-shaped, fan-shaped or outstretched-bent, up to 7 centimeters in diameter, attached to the substrate by the base, sometimes practically at one point. The place of attachment is thickened in the form of a tubercle. The edge is even or wavy, sometimes it can be divided into lobes. Usually grow in large numbers, arranged in tiles or in rows. In rows, adjacent fruiting bodies can grow together with their lateral sides, forming extended frills.
The upper side is velvety, felt, with a light edge and clear concentric stripes, with age it is covered with a green coating of epiphytic algae. Color from grayish-orange to yellowish and reddish brown and even intense lingonberry, strongly depends on age and weather conditions (older and dried specimens are dull).
The underside is smooth, dull, in older specimens it may be slightly radially wrinkled, faded, grayish-brownish, with more or less pronounced concentric stripes (in wet weather the stripes are more noticeable, in dry weather they practically disappear).
The fabric is thin, dense, tough, without much taste or smell.
Edible The mushroom is inedible due to its tough pulp.
Ecology and distribution Widespread mushroom in the northern temperate zone. It grows on dead trunks and branches of deciduous trees, most often on alder. Growth period from summer to autumn (year-round in mild climates).
Similar species Stereum hirsutum has a hairy surface, a more yellow color scheme with less distinct stripes and a bright hymenophore.
