Article: Horak, E. (1973). Fungi Agaricini Novazelandiae I-V. Beihefte zur Nova Hedwigia 43: 200 p. Description: Pileus
10-30 mm diam., hemispherical or convex at first, becoming conical, aged carpophores
mostly plane with pronounced papilla at the centre, white turning pink or pink-beige,
very densely covered by radial, white fibrils, forming a felt-like weft or sometimes
also with fine squamules, membranous, striate near the margin, dry. Lamellae
(L 8-14, l 3) adnate to adnexed, occasionally emarginate, white becoming deep
pink, gill edge white and fimbriate. Stipe 10-40 x 1-3 mm, cylindrical, often
bent, white or hyaline, densely covered by white, silky fibrils, apically also
pruinose (in young specimens), dry, hollow, fragile. Context white. Taste and
odor strongly farinaceous.
Spores
8-10 x 6-8.5 µm, 5-sided. Basidia 30-35 x 8-10 µm, 4-spored. Cheilocystidia
35-60 x 7-12 µm, capitate-fusoid, sometimes even lecythiform, often irregularly
constricted, membrane thin-walled and hyaline. Pleuro- and caulocystidia none.
Cuticle a cutis of repent, cylindrical hyphae (6-9 µm diam.), membrane not gelatinized,
pigment lacking or encrusting. Clamp connections absent, or very scanty. Habitat: On
rotten wood or sawdust of Nothofagus spp., Dacrydium cupressinum or Podocarpus
spp. New Zealand. Notes: E. niveum is closely
related to E. albidum Hesler which differs in several minor characters
only. According to Hesler the North American species does not grow on rotten
wood but on soil.
The
relationship of E. niveum with E. pluteoides Hk. is obvious but
the two species can be easily separated by the following characters: colour
and structure of the cuticle, attachment of the lamellae, presence or absence
of cystidia and localization of the pigment.
Article: Stevenson, G. (1962). The Agaricales of New Zealand: III. Kew Bulletin 16(2): 227–237. Description: Pileus 2-4 cm. diam., snow-white, hemispherical at first, then becoming plane, covered with a fine, felt like weft; flesh creamy-white. Gills adnexed, moderately crowded, creamy becoming stained pale-pink. Stipe 3-4 cm. x 4 mm., white, with ochraceous tinge at base, silky-striate, more or less equal, solid, creamy coloured flesh continuous with that of cap. Spores strongly angled, overall shape rather cuboid, 7 x 10-11um; print dark-pink; no cystidia. Habitat: rooting in soil among litter, Johnson's Hill, Wellington, 12.9.1949, Stevenson.
