Description

PILEUS: 0.5-3.5 cm diam., strongly convex when young, convex to plano-convex at maturity, typically umbonate, hygrophanous, non-viscid, innately radially fibrillose, ends of fibrils often reflexed giving pileus a finely scurfy appearance in centre, aggregated towards margins, background colour buff with faint violaceous tints, fibrils dark brown to brownish black in centre, paling towards margins, margins often dentate to lacerate with age. Cuticle composed of unspecialised, repent, interwoven, thin-walled, clamped hyphae 7-13 µm diam, with dark brown contents and often roughened walls near surface. LAMELLAE: adnexed to adnate, distant, intermixed, thick, to 5 mm deep, pallid violaceous, often turning buff with age, glaucous. STIPE: 2-7 cm long, ± equal or slightly expanded basally, 1.5-3 mm diam., tough, dry, hollow, longitudinally fibrillose-striate, pallid, violaceous when young, becoming buff from base upwards at maturity, finally entirely buff except for violaceous tints at extreme apex; flesh concolorous with exterior; basal mycelium pallid violaceous. SPORES : spore print white when fresh; spores globose to subglobose, rarely broadly elliptical, apiculate, hyaline, inamyloid, coarsely echinulate, 10-12.5-(13.5) µm diam. including spines, spines 1.5-2.5 µm long. HYMENIUM: basidia hyaline, clavate, 35-53 X 10-13.5 µm, 4-spored, sterigmata to 9.5 µm long; paraphyses simple or irregularly and sparingly branched apically. HYMENOPHORAL TRAMA : regular, composed of tinted, parallel-interwoven, long-celled hyphae; clamp connections present. CONTEXT OF PILEUS: thin, pallid, violaceous, turning buff at maturity. SMELL AND TASTE: not distinctive. CHEMICAL CHARACTERS: unknown.

Habitat

Gregarious to caespitose under Nothofagus.

Latin

Pileus convexus ad plano-convexum, umbonatus, 0.5-3.5 cm diam., radialiter fibrillosus, subtiliter exasperatus in centre, violaceo-tinctus, fibrillae atro-brunneae. Lamellae adnexae ad adnatas, distantes, crassae, ad 5 mm altae, pallide violaceae, bubalinae ubi maturae. Stipes 2-7 cm longus, plus minusve aequalis, 1.5-3 mm diam., cavus, in longitudinem fibrilloso-striatus, pallide violaceus, bubalinus ubi maturus. Sporae globosae ad subglobosas, hyalinae, echinulatae, 10-12.5-(13.5) µm diam. cum spinis, spinae 1.5-2.5 µm longae. Basidia tetraspora.

Notes

Laccaria fibrillosa is one of the two species described by Stevenson (1964) under L. masonii, and is characterised by the typically umbonate pileus covered with dark, radially arranged fibrils. The conspicuous violaceous colour of young fructifications rapidly disappears with age. L. fibrillosa is found in Nothofagus dominated habitats.
