Notes: Entoloma placidum (Fries) (11,16,27) Fig. 21 = Pluteus readii Stevenson
The examined material (COLENSO b 1204) agrees with this native Pluteus (see
there) in all characters.

Description: Pileus 3-3.5 cm. diam., convex, yellow-fawn overlain by a dark-brown velvety, fibrillose network; flesh pale yellow-fawn. Gills free, crowded, pink with whitish margins. Stipe 4 cm. x 3-4 mm., silky-fibrillose, pale yellow, grey tinge at top, bulbous base surrounded by white mycelium. Spores 5 x 6um, print pink. Pleurocystidia not very numerous, pyriform with or without pinhead; balloon cystidia on gill edge 15 x 50um; hyphal endings of pileus 20 x 60-70um, colourless, overlain by a partial palisade of large hyphal endings up to 150 x 25um with dark-brown contents, which constitute the dark velvety fibrils.
Habitat: on standing dead ribbonwood, Nelson, 15.1 1. 1958, D. & L. Read; on fallen tawa, Levin, 5.9.1955, Stevenson

Description: Pileus 2-6 cm. across, flesh thin, campanulate, then convex, not striate, the blackish disc
densely downy, the remainder covered with blackish fibrils or squamules on a greyish-white
ground, squamules arranged concentrically when old; gills adnexed, very broad behind, not
ventricose, crowded, whitish, as is also the margin; stem 5-8 cm. long, 3 mm. thick, equal,
very rigid, having white meal at the slightly thickened apex, and with black points or
squamules when seen under a lens, remainder glabrous, even, dark-blue or blackish-blue.
Habitat: On trunks or on the ground.
Distribution: New Zealand. Europe.
Notes: Distinguished from Leptonia lampropoda by the squamulose pileus and the minute black
points on the upper part of the stem.
