Article: Horak, E. (1973). Fungi Agaricini Novazelandiae I-V. Beihefte zur Nova Hedwigia 43: 200 p. Description: Pileus
25-65 mm diam., young and old specimens umbonate, dark brown or soot-brown with
distinct purplish tints, densely covered by concolorous squamules or scales,
dry, neither striate nor hygrophanous, membranous. Lamellae (L 16-30, 1 3(-5))
adnate or emarginate and decurrent with short tooth, whitish-purple at first
becoming brown-pink with lilac or purplish tints, gill edge whitish and fimbriate.
Stipe 30-70 x 3-6 mm, cylindrical or attenuated upwards, concolorous with pileus,
covered with purple, lilac or dark brown fibrils, whitish at the base, dry,
fistulose, fragile, frequently twisted. Context lilac, especially in the cortex
of the stipe. Odor and taste acidulous.
Spores
7.5-8.5 x 5-6 µm, 5-6-sided. Basidia 35-40 x 8-10 µm, 4-spored. Cheilocystidia
30-65 x 8-20 µm, polymorphic, varying between vesiculose, clavate, fusoid or
uteriform, occasionally even lecythiform, membrane hyaline, thinwalled. Pleuro-
and caulocystidia none. Cuticle a cutis of cylindrical, fasciculate, repent
or suberect hyphae (7-15 µm diam.) with brown plasmatic pigment not gelatinized.
Clamp connections absent. Habitat: On soil among mosses and litter in
forests (under Nothofagus spp., Dacrydium cupressinum, Podocarpus
spp., Metrosideros umbellata, Leptospermum spp.). New Zealand. Notes: This
species is distinguished by its purplish or lilac tints, umbonate pileus and
spores which are distinctly smaller as those of E. porphyrophaeum (Fr.)
a closely related species known from Europe.
Sometimes
aged and weathered specimen do not show the lilac colours on the pileus or the
lamellae but this striking character may then often still be recognized in the
cortex of the stipe.
