Sunset Webcap Cortinarius (Cortinarius) limonius (Fr.) Fr. (illustrated 40% life size) Cap 3–9cm across, convex then expanded and slightly depressed or umbonate; bright yellow-orange, darker at centre. Stem 50–120×8–20mm; yellow-orange above, becoming rusty-tawny towards the base, covered in scattered patches of yellow velar remains; cortina pale yellow. Flesh yellow to golden, often tawny below cap cuticle and stem base; smell faint, like raw potato. Gills adnate; yellow, soon golden, finally rusty-tawny. Spores 7–9×5.5–7¼, broadly ovate to subglobose, rough. Spore print rust. Habitat in coniferous woods; autumn. Occasional in northern areas, elsewhere rare, vulnerable on Red Data List. Poisonous. Note in my first book this fungus was named C. callisteus, but C. limonius is now considered the correct name.
