🔬 Morphology
Cap
Orange webcap
The cap is 5-10 cm across, hemispherical with an inrolled margin in young mushrooms, becoming convex to flat over time. The color is chestnut-brown, honey-brown, darker in the center, paler at the margin. The surface is very slimy in wet weather — a hallmark of the species. The cap skin peels off easily, as in a slippery jack. In dry weather the cap is simply shiny, without noticeable slime.
Cortinarius multiformis
The cap is 5-10 cm across, hemispherical with an inrolled margin in young mushrooms, becoming convex to flat with a low umbo over time. The color is orange-yellow, honey-ochre, reddish-yellow, darker when young, fading to pale ochre with age. The surface is smooth, slightly slimy in wet weather. Older mushrooms often show fine radial cracks.
Hymenophore
Orange webcap
The hymenophore is gilled — the gills are attached to the stem and moderately crowded. In young mushrooms they are pale cream to pale ochre, later turning rusty brown as the spores ripen. The spore print is rusty brown — a diagnostic feature of the genus Cortinarius. In young mushrooms the gills are covered by a cobwebby partial veil (the cortina).

Stem
Orange webcap
The stem is 6-12 cm tall, 1-2 cm thick, cylindrical, long, often tapering toward the base. The color is whitish to cream, with reddish tints toward the base. The surface is smooth, slimy in the upper part, with fine lengthwise fibers. On the stem, remnants of the cobwebby cortina form a thin band dusted with rusty-brown spores.
Cortinarius multiformis
The stem is 5-9 cm tall, 1-2 cm thick, cylindrical, with a pronounced bulbous base (like an onion bulb). The color is whitish to pale ochre. On the stem you'll see remnants of the cobwebby cortina dusted with rusty-brown spores.
Flesh
Orange webcap
The flesh is firm, white to cream. When cut it does not change color. The smell is faint and neutral, with no distinctive notes.
