The velvet foot wood krempling or short velvet foot krempling ( Tapinella atrotomentosa ) is a type of fungus from the family of wood kremplings related (Tapinellaceae). The laterally stalked fruit bodies have a brown hat, yellowish lamellas and a dark to black-brown, velvety stem. The species only colonizes softwood stumps.
features
Macroscopic features
The velvet-foot wood krempling forms fruiting bodies divided into hat and stem, the stem of which is usually eccentric or to the side. The hat becomes 2–7 (–20) cm wide and is semicircular, shell or tongue-shaped, thick and firm; its surface is fine-felted and velvety brown when young, balding and cracked with age, the edge of the hat remains rolled up for a long time. The lamellas that run down the handle are narrow, often forked and connected by transverse walls . The lamellar layer can be removed from the hat. The color of the lamellae is pale yellow to light, and slowly browning at pressure points. The bulbous stem is 8 cm long and 2–4 cm wide, its surface is velvety-tomentose, dark brown-brown-black and clearly set off from the lamellae. The flesh is thick, soft, whitish to pale yellow. It smells sour and tastes slightly bitter. The spore powder is colored yellow-brown.
Microscopic features
Microscopically, the species is characterized by 5–6 (7) µm × 3.5–4.5 µm large spores and cylindrical to narrowly clubbed basidia .
Ecology and phenology
The velvet foot wood krempling is a wood-dwelling saprobiont that is only found on dead stumps of conifers. It colonizes acidic beech and spruce-fir forests, spruce and pine forests and can also be found in parks. Although the species prefers acidic soils somewhat to basic and neutral subsoil, it is not a typical acid indicator. The species prefers a medium nitrogen supply, with a strong nitrogen load it disappears.
In Central Europe, the fruiting bodies appear in late summer and autumn, and fructification ends in early October. Outstanding specimens can still be found a few weeks later.
distribution
Mainly, the velvet foot wood krempling is widespread from the northern subtropical zones to the coniferous forest regions: It is found in Japan, the USA and Mexico and is also found in South America. It is common in Europe and common everywhere.
meaning
The velvet foot Krempling is only edible when young and is generally not considered an edible mushroom because of its bitterness; as a wood decomposer, it is of no economic importance. The blue brew from the pulp can be used to dye textiles.
