Description: Pileus 15-25 mm diam.,
convex to convex-umbonate, chocolate brown, with conspicuous radially arranged
darker brown or black zones, innately fibrillose, sometimes also minutely squamulose
near the centre, dry, estriate, not hygrophanous. Lamellae (L 12-18, l 3) adnexed
or emarginate, beige when young, later becoming pink, gill edge concolorous,
not fimbriate. Stipe 30-45 x 2-3 mm, cylindrical or slightly attenuated downwards,
lilac-blue, densely covered by silky fibrils, white near the base, dry, cartilaginous,
fistulose, solitary. Context lilac or bluish in the stipe, whitish in the pileus.
Odor and taste strongly acidulous (like Lepiotula cristata).
Spores
6-7.5 x 6-7.5 µm, subglobose, with 5-7 blunt angles. Basidia 30-36 x 10 µm,
4-spored. Cheilo- and pleurocystidia 20-40 x 15-25µm, clavate or vesiculose,
thin-walled, without pigment, hyaline. Caulocystidia absent. Cuticle a palisade
of erect or suberect, cylindrical hyphae (5-10 µm diam.), membrane thin-walled,
not gelatinized, with brownish, plasmatic (and also epimembranous) pigment.
Clamp connections frequent.
Habitat: On
soil among mosses in Nothofagus-forests (with Dacrydium cupressinum,
Podocarpus hallii, P. ferrugineus). New Zealand.
Notes: The
macro- and microscopical characters of this Entoloma are rather aberrant
in that genus. Especially the vesiculose cheilocystidia, the subglobose spores
and the palisade-like cuticle emphasize its isolated taxonomic position.
