🔬 Morphology
Cap
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.
Red banded webcap
Cap 5-12 cm across, hemispherical with an inrolled margin in young mushrooms, later becoming convex with a low umbo. Color red-brown, brick, russet-brown, with a pinkish tint when young. Surface velvety and dryish, with fine radial fibers. The cap margin is thin, with pinkish veil remnants in young mushrooms.
Hymenophore
Cortinarius multiformis
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. In young mushrooms the gills are covered by a cobwebby partial veil (the cortina).
Red banded webcap
Gills — attached to the stem, moderately spaced. In young mushrooms light pinkish brown, becoming with age rusty brown, dark brick as the spore powder ripens. Spore print rusty brown. In young mushrooms the gills are covered by a cobweb-like partial veil (cortina).
Stem
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.
Red banded webcap
Stem 8-15 cm tall, 1-2.5 cm thick, cylindrical, long, thickened toward the base. Color brownish cream, with 2-4 distinct red-orange ring-like "bracelet" bands on the lower half — the diagnostic feature of the species. The surface has fine lengthwise fibers. Near the top there is a faint band left by the cobwebby cortina.
Flesh
Cortinarius multiformis
The flesh is firm, white to pale cream. When cut it does not change color or turns slightly yellow. The smell is faint and neutral.
