Laccaria lilacina G. Stev. 1964
K(m)235261, Stevenson 924. The packets contain relatively large fruitbodies, much closer in appearance to L. violaceoniger than L. fibrillosa. The cap is milk-chocolate brown innately firbrillose/striate in the centre, with some squamules at cap edge. It does not have the dark brown/black central raised fibres of L. fibrillosa. Spores (excluding ornamentation and apiculus) length=6.6–9.0µm (µ=7.7, σ=0.61), width=7.0–8.1µm (µ=7.5, σ=0.33), Q=0.9–1.2µm (µ=1.03, σ=0.06), n=20, spines to 1.3um. No cystidia observed.

PILEUS: 2-5.5 cm diam., strongly convex when young, plano-convex, applanate, or centrally depressed with reflexed margins at maturity, often radially split, hygrophanous, non-viscid, sometimes radially sulcate almost to centre, finely radially fibrillose when young, fibrils cracking to form numerous, minute squamules and scales giving pileus a scurfy appearance at maturity, background colour buff, fibrils, scales, and squamules dark brown to brownish black. Cuticle composed of unspecialised, repent, subparallel, thin-walled, clamped hyphae 7-10 µm diam. with dark brown contents near surface of pileus and often aggregated into clumps. LAMELLAE: adnate, distant, intermixed, thick, to 5 mm deep, pallid violaceous when young, turning buff with age, glaucous. STIPE: 5-10 cm long, ± equal or tapering apically, 3-5 mm diam., tough, dry, hollow, longitudinally fibrillose-striate, dull pallid fawn to buff, paling basally; flesh concolorous with exterior. SPORES: spore print not obtained; spores globose to subglobose, apiculate, hyaline, inamyloid, moderately echinulate, 8.5-11 µm diam. including spines, spines to 1.2-(1.8) µm long. HYMENIUM: basidia hyaline, clavate, 35-50 X 8-11 µm, 4-spored, sterigmata to 9 µm long; paraphyses sparse, simple, inconspicuous, HYMENOPHORAL TRAMA: regular, composed of tinted, parallel-interwoven, long-celled hyphae; clamp connections present. CONTEXT OF PILEUS: pallid fawn. SMELL AND TASTE: unknown. CHEMICAL CHARACTERS: unknown.
Gregarious or caespitose under Nothofagus.

Laccaria lilacina is characterised by the closely and minutely squamulose pileus of mature fructifications, pallid violaceous lamellae, and longitudinally fibrillose-striate stipe. Young fructifications resemble those of L. fibrillosa, but at maturity the fine radiating fibrils on the pileus of L. lilacina become cracked into minute squamules, whereas in L. fibrillosa the dark coloured fibrils remain unaltered. In addition, spores of L. lilacina are smaller with shorter spines. The species is restricted to southern beech forests.

Pileus 4-5.5 cm diam. fawn, covered with dry fulvous fibrils, which crack into very small scales, convex to plane with upturned edge, which is often split; flesh thin, pale fulvous. Gills adnate, distant, lilac, and mealy. Stipe 10 cm x 3-4 mm dull fawn whitish at base, solid or hollow, subfibrous, silky striate. Spores 7-8 µm diam., spines 0.5-1 µm long, non-amyloid, thick-walled (Fig. 4); print white.

Pileus 4-5.5 cm diam., hinnuleus, fibrillis siccis fulvis in squamas minimas fissis obtectus, convexus usque planus, margine sursum revoluto saepe fisso; came tenui, pallide fulva. Lamellae adnatae, distantes, lilacinae, farinosae. Stipes 10 cm x 3-4 mm, obscure hinnuleus, basi albidus, solidus vel cavus, subfibrosus, sericeo-striatus. Sporae 7-8 µm diam., spinis 0.5-1 µm longis, haud amyloideae, parietibus crassis; in cumulo albae.
The European L. amethystina is more generally purple coloured and has larger spores with longer spines than this species, which is however close to it.
Typus: M. Morrison in Stevenson 924.
