Article: McNabb, R.F.R. (1972). The Tricholomataceae of New Zealand. 1. Laccaria Berk. & Br. New Zealand Journal of Botany 10(3): 461-484 (http://www.rsnz.org/publish/abstracts.php). Description: PILEUS: 0.5-3.5 cm diam., convex to plano-convex when
young, plano-convex or occasionally applanate at maturity, hygrophanous, non-viscid,
pellucid-striate at margins under wet conditions, glabrous or minutely furfuraceous
in centre, violaceous with buff tints when young, violaceous colour disappearing
with maturity and finally entirely buff. Cuticle composed of unspecialised,
repent, parallel or slightly interwoven, thin-walled, clamped hyphae 7.5-12.5
µm diam. LAMELLAE; adnexed to adnate, distant, intermixed, thick, to 4 mm deep,
pallid violaceous when young, violaceous colour disappearing with maturity and
finally pallid brownish pink, occasionally faint violaceous tints remaining,
glaucous. STIPE: to 10 cm long, tapering apically, 1-2.5 mm diam. apically,
3-6 mm diam. basally, tough, dry, hollow, longitudinally fibrillose-sulcate,
violaceous when young, becoming buff basally with 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, apiculate, hyaline, inamyloid, coarsely echinulate, 10.5-14.5
µm diam. including spines, spines 2-3.5 µm long, to 2.5 µm diam. basally. HYMENIUM:
basidia hyaline, stout, broadly cylindrical to clavate, 30-41 X 7.5-12 µm, 4-spored,
sterigmata to 9 µm long; paraphyses numerous, simple or sparingly branched,
filamentous, to 3 µm diam., projecting beyond basidia. HYMENOPHORAL TRAMA: regular,
composed of tinted, ± parallel, long-celled hyphae; clamp connections present.
CONTEXT OF PILEUS: thin, concolorous with exterior. SMELL AND TASTE: not distinctive.
CHEMICAL CHARACTERS: FeSO4 on pileus and context—rapidly dark grey; KOH and
NH4OH on pileus and context—no reaction. Habitat: Densely gregarious to caespitose under Nothofagus. Notes: Stevenson (1964) included two distinct species in her
original description and illustrations of Laccaria masonii. one with
a glabrous, violaceous to buff coloured pileus. and the other with a radially
fibrillose pileus. The type collection consists solely of fructifications with
gabrous pilei and the name is accordingly restricted to this species. The second
species is described under L. fibrillosa.
L. masonii is characterised by violaceous fructifications when young, coarsely spinose
spores, and the absence of radial markings on the pileus. Although the violaceous
tints disappear with maturity, the species may still be recognised by the spore
ornamentation. L. masonii is restricted to southern beech forests.
Article: Stevenson, G. (1964). The Agaricales of New Zealand: V. Kew Bulletin 19(1): 1-59. Description: Pileus 0.5-3 cm diam., fawn with or without lilac tints, occasionally
with overlying fulvous or fuscous fibrils, striate, hemispheric rarely becoming
plane, sharply umbonate, or umbilicate or both. Gills adnexed, seceding,
distant, mealy, lilac or buff. Stipe 3-8 x 0.1-0.3 cm, lilac or fawn, hollow,
subfibrous, often twisted, firmly bound to moss or litter by a weft of hyphae
at base. Spores 7-10 µm diam., non-amyloid, thick-walled, with spines 2-3 µm
long. Habitat: HABITAT: attached to moss or litter under Nothofagus solandri and
