Article: Horak, E. (1973). Fungi Agaricini Novazelandiae I-V. Beihefte zur Nova Hedwigia 43: 200 p. Description: ‘Pileus
35 mm diam., plano-convex, purple-brown; covered with a close cottony weft.
Gills adnexed, moderately distant. creamy becoming pink. Stipe 55 x 5 mm. tapering
upwards. cottony-striate. purple above to white at bulbous base’ (Description
according to Stevenson 1962: 1.c.).
Spore print dark pink.
Spores 11- l 5 x l 2-14 µm. quadrate, at times obscurely 5-sided. basidia 50-55
x 14 µm. 4-spored. Cheilocystidia 55-110 x 10-l5 µm. irregularly fusoid, several
times constricted, thin-walled, in KOH with yellow-brownish, plasmatic pigment,
conspicuously clustered at gill edge. Pleurocystidia absent. Cuticle a cutis
consisting of cylindrical, repent hyphae (3-8 µm diam.), terminal cells suberect
and apically rounded, in KOH with yellow-brown, plasmatic pigment. Clamp connections
present. Habitat: In litter under mixed forest. New Zealand. Notes: This
interesting species is characterized by the cuboid spores, the conspicuous cheilocystidia
and the deep purple-brown colour of pileus and stipe. The rather unusual colour
for a species of Entoloma changes in KOH to yellow-brown and can be observed
in the hyphae of the pileus and trama and in the cheilocystidia. The dimensions
of the spores as described by Stevenson in the original diagnosis are by far
too small and there is no doubt also about the presence of cheilocystidia.

Gills adnexed, moderately distant, creamy becoming pink. Stipe 5.5 x 0.5 cm., tapering upwards, cottony-striate, purple above to white at bulbous base.
