Description: Pileus
30-60 mm diam., pulvinate or convex becoming plano-convex, brown olive when
young turning date brown-olivaceous, densely covered with radially arranged,
persistent, brown or ochraceous squamules or scales from the veil, viscid to
glutinous, margin sometimes slightly striated, often seamed with membranaceous
veil remnants. Lamellae adnate to adnexed, occasionally decurrent, large, greyish-blue
when young turning beige-olivaceous and bright rust brown to argillaceous at
maturity, gill edge concolorous, conspicuously notched or serrate, with an irregular,
vertical striation at the gill face, intermixed. Stipe 25-60(80) x 5-15 mm,
up to 25 mm diam. at the base, equal or attenuated towards the apex, base abruptly
marginate but never with marginate, conspicuous bulb, rather piston-like. Bluish-greenish
when young, turning ochraceous, densely covered with golden or ochraceous squamules
or small scales from the veil, sometimes arranged in irregular bands or patches,
fibrillose, dry, hollow. Cortina absent. Context whitish to brownish, olive
brown beneath the cuticle, green-blue in the upper parts of the stipe. Odor
and taste not distinctive. Chemical reactions on pileus: KOH - reddish brown;
HCl - yellow; NH3 - negative.
Spore print deep rust brown. Spores 11-15.5 x 7-8.5 µm, broadly ovate to ellipsoid,
densely covered with small (up to 0.5 µm diam.) isolated warts, warts not coarser
towards the apical region; germ pore, plage or mucro absent. Basidia 35-46 x
12-14 µm, 4-spored. Cystidia absent. Cuticle consisting of strongly gelatinized
cylindrical hyphae (4-6 µm diam.) forming a cutis, encrusted with yellow-brown
pigment, clamp connections present. Patches of the veil composed of cylindrical,
not-gelatinized hyphae, 6-15 µm diam., strongly encrusted with brown pigment
Habitat: Amongst litter under Nothofagus spp.
(N. fusca, N. menziesii, N. cliffortioides). New Zealand.
