Description: Pileus 3-8 cm diam., olive-buff to olive-brown, sprinkled at centre with very small dull brown scales, convex at first with a strongly down-rolled margin, becoming plane to shallow concave, moist when fresh with a conspicuously striate margin, drying matt; flesh creamy white. Gills decurrent to a most sinuate, creamy white becoming dull fawn, moderately crowded with many short members. Stipe 4-7 x 0.4-0.8 cm, fawn above evanescent ring, brown to dark purplish brown below, smooth or striate, tough, solid, bases swollen and united. Spores 8-9 x 5.5-6.5µm, non-amyloid rather thick-walled (Fig. 24). Spore print white.
Habitat: In dense groups round standing dead broad-leaved trees, or on their fallen timber, Wellington Botanic Garden, 2.6.1949, Stevenson, Eastbourne, Wellington, 4.6.1949, Stevenson (type); Butterfly, 2.6.1958, Stevenson; Otari, 22.6.1958, Stevenson, Kapiti, 22.6.1958, M. Davidson.

Description: Type: Radicicolous Fungi; Description: Basidiomata pileate, centrally stipitate. Pileus 30–80 mm in diameter, olive buff to olive brown, sprinkled with very small dull brown scales at the centre, convex at first, becoming plane to shallow concave; flesh creamy white. Gills decurrent to almost sinuate, moderately crowded, creamy white becoming dull fawn. Stipe tapering towards the base, fawn above evanescent annulus, brown to dark purplish below, smooth or striate, solid, 40–70 mm long. Basidiospores ellipsoid to elongate-ellipsoid, 7–9 × 5–6 m, non-amyloid; spore print white.

Description: Pileus 5-12 cm. across, disc fleshy, remainder thin, convex then expanded, often becoming more or less depressed at the centre, often sooty or covered with olive down when young, soon paler; usually ochraceous with a tinge of honey-colour, sprinkled all over with small spreading blackish-brown scales, margin striate; gills adnate, then becoming more or less decurrent, rather distant, white with a pink tinge, then brownish and powdered with the white .spores; stem 6-12 cm. long, 1-1.5 cm. thick, rigid, more or less grooved, dingy-ochraceous, floccose or almost naked below the ring, base often covered with yellowish down, stuffed, then hollow, elastic, ring near the apex; spores elliptical, 9 x 5-6 µ.
Habitat: At the base of trunks or on the ground, springing from buried wood.
Distribution: Maungaroa, New Zealand. Europe, North America, South America, Australia, India.
Notes: Usually densely tufted, although sometimes solitary, and then usually larger; very variable; stem and pileus often quite glabrous, especially when old. A very destructive parasite to timber trees in Europe, the black cord-like strands of mycelium running between the wood and the bark, also travelling in the ground from one tree to another. These strands of mycelium were at one time considered as constituting a distinct genus of Fungi called Rhizomorpha.

Description: This common tree-destroying fungus with very characteristic bootlace rhizomorphs is regularly seen in plantations. In Japan it is recognized as the mycorrhizal fungus of the saprophytic orchid Gastrodia R. Br., one species of which is fairly common throughout New Zealand.
