Rozites caperata
(
Pers.: Fr.) Karst

Pileus: 3 - 12 cm broad; conic to broadly parabolic at first, then becoming planar convex to umbonate and finally campanulate; margins inrolled at first then straight and finally flaring upwards; surface dry, prominently wrinkled radiating from disc, unpolished, at first pruinose finally becoming glabrous; deep orange brown, fading to greyish light orange brown; context 1.3 cm at junction of stipe, firm, thick, white to pallid buff, ivory; taste mild; odour indistinct.

Lamellae: Ascending to notched, average to crowded spaced, pallid at first, then light brown and finally dark brown at maturity; edges serrate and paler than faces; 3 lamellulae.

Stipe: 5 - 9 cm long X 1.5 cm wide at apex, 2.5 cm wide at base; equal to tapering upwards, flexuous, striate fibrous, glabrous but occasionally with remnant veil tissue at base, white to pallid or ivory; context white, solid, fibrous;

Annulus: Membranous, towards apex of stipe, white.

Microcharacteristics: Spore print brown; spores 10 - 15 X 7- 10 µm ellipsoid, rough with warts.

Comments: This robust species has a distinctive grooved to wrinkled cap. Molecular analysis of this species indicates that it belongs in the genus Cortinarius. The membranous annulus will distinguish this species from other Cortinarius species. and has the appearance of a large ‘cort’ (Cortinarius species). The spores of Rozites caperata are similar to those of Cortinarius.
