features

Macroscopic features

The hat of the felty yellow foot is 3–7 cm wide and yellow-orange, especially in old age it is also colored wine-red in places. The middle of the hat is rounded to wide. The felt-like, fibrous, finely flaky hat skin is dry and only greasy in damp weather. The orange-yellow lamellae in the young fruiting body darken with age as the spores ripen and can then be colored wine-reddish to blackish in places. They run down the stick for a short time , are thick and standing at a distance. The spore powder is blackish or dark olive brown. Like the hat, the cylindrical stem is yellow to orange-brown in color, dry and slightly tomentose. The flesh is orange-yellow and, with age, wine-red, at the base of the stem it is chrome-yellow. At the tip of the handle there is an indicated ring zone as a remnant of the velum . The smell is pleasant, slightly fruity, the taste mild to slightly sour.

Microscopic features

The elongated spindle-shaped spores have a smooth surface and have no germ pore. They measure 15-20 × 6.5-8 micrometers. The club-like basidia with four sterigms are 50–60 micrometers long and 10–12 micrometers thick. The cheilo- and pleurocystids are cylindrical in shape, have a stem-shaped base and measure 80–115 × 14–18 micrometers.

Species delimitation

The felty yellow feet can be confused with other yellow feet such as the copper-red yellow foot ( Chroogomphus rutilus ). These differ in the reddish-brown hat colors of the young mushroom and a smooth (not felty or flaky) hat surface that is greasy when wet.

Edible mushroom collectors should not confuse the felty yellow foot with veils like the deadly poisonous pointed hunched rough head ( Cortinarius rubellus ). This one has more red-brownish colors, rust-brown spore powder, a faint radish odor and no yellow flesh in the base of the stem.

Ecology and phenology

The felt yellow foot is a mycorrhizal fungus of the mountain coniferous forest, preferred partners are spruces or two-needle pines. It occurs frequently locally at suitable locations. The solitary to gregarious growing fruit bodies appear from July to October.

distribution

The occurrence of the species is limited to Europe.

meaning
