Dappled Webcap (Cortinarius bolaris)
Index Fungorum Cortinarius bolaris (Pers.) Zawadzki
MycoBank Cortinarius bolaris (Pers.) Fr.
Dappled Webcap, Lazy Webcap. Possibly this name reflects the growth pattern of the fruiting bodies; sometimes it really seems as if they are too "lazy" to grow.
Bolaris, e — mycological: dark red, brick-red. From bolus + -aris.

2.5–8 cm in diameter, initially convex or broadly bell-shaped, then becoming broadly convex or nearly flat. Dry surface, covered with scales ranging from red to brownish-red; as the cap expands, the scales become more scattered, exposing whitish, yellowish, or pinkish flesh. Gills broad, adnate, moderately spaced. In young specimens gray or dirty yellow; with age, like in most Cortinarius species, they become rusty-brown from maturing spores.
Short and thick (4–10 cm tall, 1–1.5 cm in diameter), often curved and twisted, dense and sturdy. Surface covered with reddish-red scales. Reddish bands are visible on the upper part of the stipe.
Whitish, gradually turning yellow when cut or exposed to air. Flesh in the stipe is fibrous.
Weak, musty.
Spore print rusty-brown. Spores 6–8 × 5–6 µm; subglobose to ovoid; moderately warted.
Forms ectomycorrhiza with trees of various species, both deciduous and coniferous. Found in mixed forests. Prefers acidic, sandy soils. Fruits in moist places, among mosses. Occurs singly and in groups consisting of fruiting bodies of different ages.
Literature mentions the Peacock Webcap (Cortinarius pavonius), which in young age is distinguished by purple gills; however, finding information about its occurrence in Russia is quite difficult. Otherwise, the Dappled Webcap has no known look-alikes.
Cortinarius is one of the largest genera in the order Agaricales. Different authors cite varying numbers of species in the genus, usually up to 700; however, according to the most comprehensive reference work, the "Dictionary of the Fungi," the number of species exceeds 2000.
