Collections Examined

Holotype (K): 'Wellington, N.Z.; leg. Stevenson 599, 30.V.1949'. - Herb. HK. ZT 68/470 (PDD 27014): 'Puponga, N of Collingwood, prov. Nelson, N.Z.; leg. Horak, 17.V.1968'. - Holotype of Entoloma inconspicuum Stev. (K): 'Kaingaroa, N.Z.; leg. Stevenson 1260, 12.III.1958'.

Description

Pileus 15-45 mm diam., hemispherical when young becoming convex or campanulate, sometimes with distinct, small umbo or even slightly depressed at the centre, dark brown, covered by radially arranged, ± repent, soot-brown fibrils, margin striate and exceeding gills, dry. Lamellae adnexed to free, moderately crowded, whitish to pale pink, turning pink, with white later brownish, fimbriate edge. Stipe 40-70(-150) x (2) 3-8 mm, cylindrical, white or with soot-brown tinge, at the base often with white weft, fibrillose, dry, hollow, fragile. Context brownish, watery. Odor and taste not distinctive. Chem. reactions: KOH and HCl on pileus - negative.
Spores 10-13 x 8-12 µm, like twinned tetrahedra. Basidia 35-42 x 10-12 µm, 4-spored. Cheilocystidia 40-130 x 10-18 µm (terminal cell), cylindrical, often curved near the apex, membrane thin-walled, with brownish, plasmatic pigment. Cuticle a cutis of repent, cylindrical hyphae, membrane thinwalled, not gelatinized, with conspicuous, brown (in KOH) plasmatic or vacuolar pigment. Clamp connections numerous.

Habitat

On soil in forests of Beilschmiedia tawa, Leptospermum spp. or Pinus. Rarely also observed in woods of Nothofagus spp. New Zealand

Notes

E. procerum can be considered as a common fungus in different kind of forests in New Zealand and occurs also in some exotic forests under Pinus and Pseudotsuga (Stevenson 1962: I.c.).All characters of the type collection of E. inconspicuum Stev. correspond in every respect with those of E. procerum. There is no doubt about the synonymy of these two species.
