Entoloma colensoi G. Stev. 1962
Holotype (K): 'Waikanae, N.Z.; Stevenson 791, 1.1.1951'.
‘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.

Stevenson 1962: 1.c.
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.
