Yellow cobweb cap:
Diameter 7-12 cm, hemispherical in youth, becoming cushion-shaped, semi-prostrate with age; along the edges, noticeable shreds of cobweb bedspread often remain. Color – orange-yellow, in the central part, as a rule, darker; the surface is sticky, although in very dry weather it may dry out. The flesh of the cap is thick, soft, white-yellowish in color, with an almost pleasant smell, not typical for cobwebs.
Records:
Weakly adherent, narrow, frequent, light cream when young, changing color with age, acquiring a smoky, and then bluish-brown color. In young specimens, they are completely covered with a light cobwebbed veil.
Spore powder:
Rusty brown.
Leg:
The leg of the yellow cobweb is 8-15 cm high, 1-3 cm thick, strongly thickened in the lower part when young, acquires the correct cylindrical shape with age. In young specimens, bracelet-like remains of cortina are clearly visible.
Spread:
The yellow gossamer grows from mid-August to the end of September in deciduous forests, forming mycorrhiza mainly with birch. Prefers dry places; can be considered a companion of the black mushroom (Lactarius necator). The place and time of the most intensive fruiting of these two species often coincide.
Similar species:
The yellow cobweb is one of the easiest cobwebs to identify. However, there are indeed a lot of similar species. Cobweb yellow is classified only by a combination of features – starting from the shape of the fruiting body and ending with the time and place of growth.
