Cortinarius violaceocystidiatus

Ciri dan struktur

This species produces secotioid fruit bodies. The pileus ranges from 20 to 35 mm in diameter. It is broadly rounded with an incurved margin that is not attached to stipe at maturity. The pileus margin is entire to cracked, occasionally appendiculate, tending to be slimy, dark violet to almost black, not hygrophanous, with pale violet mottling. The hymenophore locules are up to 3 mm long, ellipsoid in shape and coloured brown, attached to the upper section of the stipe then becoming free. The columella is percurrent. The stipe ranges from 25 to 80 mm long and 7 to 12 mm wide, centrally attached, equal to tapering, white to pale violet in colour with longitudinal striations, occasionally with tufts toward the base. The stipe has a fragile attachment to the pileus. The stipe context is white with a violaceus sheen to violet. Neither the cuticle of the pileus nor the stipe exhibit a colour change upon application of potassium hydroxide. Cortinarius violaceocystidiatus is unique in Section Cuphomorphi in being secotioid, whereas the other two species C. cuphomorphus and C. juglandaceus are both agaricoid. Cortinarius violaceocystidiatus is distinguished from the other purple secotioid fungi of New Zealand in having a dark violet to almost black pileus with pale violet mottling, presence of infrequent violet cystidia, and narrower basidiospores (12–15 × 5–7 μm).
