Cortinarius pseudotorvus

Ciri dan struktur

Cortinarius pseudotorvus is an oak-associated species that differs from C. torvus by the smaller and slender basidiomata, and by the slightly more felty surface of pilei; it has broadly ellipsoid to sub-amygdaliform basidiospores (10.9 × 7.1 µm in average). Basidiomata small sized and slender. Pileus campanulate when young, becoming subumbonate and sometimes flat to plano-convex in mature stages, 15–30 mm in diameter, with margins deflexed, undulate, sometimes moderately to strongly striate; cuticle light brown (8.3YR 6.7/2.5), smooth to finely or even coarsely fibrillose (felty), with dark brown (4.7YR 2.6/5.5) fibrils radiating from the center. Lamellae adnate, broad, distant and relatively thick, with an evenly smooth margin, dark brown with age (4.1 YR 1.8/3.1); lamellulae present, regular. Stipe cylindrical, up to 56 mm long, 4–9 mm at apex and 1.1–1.3 cm thick at base, which is slightly bulbous, solid; surface brown (7.8YR 4.4/4.7) becoming whitish (3Y 7.2/1.5) in upper half and the base, finely fibrillose, the 3⁄4 of stipe covered with universal veil remnants when young, and partial veil present, whitish in young specimens and brownish when mature, forming in general a persistent annulus. Context of pileus and stipe of the same color as the cuticle. Smell indistinct and taste not recorded. Basidiospores broadly ellipsoid to sub-amygdaliform, [90/6/3] (9.2–) 9.9–11.6 (–12.5) × (6.1–) 6.7–7.7 (–8.1) µm, avl × avw= 10.9 × 7.1 µm, light yellowish brown to dark brown in 5% KOH, reddish brown in Melzer’s reagent, densely ornamented. Basidia clavate, 25–35 × 7–8 µm, 4-spored, clamped at the base, hyaline in 5% KOH, darker when stained in Congo red.
