Brief Description: [See More | Edit]

Pileus 10-38 mm,campanulato-convex to convex, not or only indistinctly umbonate, margin inflexed when young, brown to isabella-brown, but somewhat darker around centre, recurvately scaly around centre, outwards more subsquarrosc to even coarsely squamulose; velipellis not observed. Lamellae, L =30-45, 1=1- 3, to 6 mm broad, not or hardly ventricose, rather broadly adnate, cinnamon-brown to brown, finally even with an olivaeeous tinge; edge fimbriate to Ilocculose. white. Stipe 25-92 × 2-6 mm, equal or attenuated ncar base, solid, then becoming somewhat fistulose, pale brown at apex, brown half-way, discolouring in lower half to greenish blue or dark greyish green, sometimes even olivaceous blaek at base, coarsely squamulose to indistinctly squarrose in lowf r half, at apex minutely pruinose- subflocculose. Context whitish in pileus and apex ofstipe. on exposure soon discolouring to pinkish or pale vinaccous, bluish green in lower pah of stipc. Smell faint, acidulous a sweetish component, PeJargol1;’um-like or reminding of I. bongonlii var. bongardii, sometimes disagreeable, somewhat fishy. Taste indistinct.

Chcilocystidia 30-54(-55) x (7-)8-11(-13) pm, (broadly) cylindrical, thin-walled, sometimes with brown contents. Basidia 30-41 × 8-10 #-1m, 4-spored. Caulocystidia only present al (extreme) apex of stipe, similar to chcilocystidia.
