Holotype (PDD 27019); Isotype (Herb. HK. ZT 68/176): 'S of Lake Hochstetter, prov. Westcoast, N.Z.; leg. Horak, 17.III.1968'.

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.

On soil among mosses in Nothofagus-forests (with Dacrydium cupressinum, Podocarpus hallii, P. ferrugineus). New Zealand.

Pileo 15-25 mm lato, convexo vel umbonato-expando, brunneo, zonis obscurioribus vel nigris radialiter ornato, sicco, minute innato-fibrilloso, haud striato hygrophanove. Lamellis ex adnexo emarginatis, griseo-argillaceis demum brunneolo-roseis, acie concolori instructis. Stipite 30-45 x 2-3 mm, cylindraceo vel attenuato basim versus, amoene lilacino-azureo, albido ad basim, fibrillis argenteis instructo, sicco, cartilagineo, fistuloso. Odore saporeque acidulo. Sporis 6-7.5 x 6-7.5 µm, subglobosis, polygonatis. Basidiis 4-sporigeris. Cheilo- et pleurocystidiis 20-40 x 15-25µm, clavato-vesiculosis, tenui-tunicatis, haud pigmentatis. Caulocystidiis nullis. Epicute ex hyphis cylindraceis palisadam formantibus, membrana haud gelatinosa, pigmento brunneo dissoluto vel incrustato instructis. Septis fibuligeris. Ad terram in silvis nothofagineis. Novazelandia.

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.
