Type: Mycorrhizal Fungi; Description: Basidiomata pileate. Pileus deep reddish brown to cinnamon brown, 50–90 mm in diameter, convex becoming applanate, felted to finely tomentose, dry; flesh dirty white to yellowish. Pore surface excavated around apex of stipe; tubes yellowish brown, up to 7 mm long; pores carmine, angular, 0.5–1 mm in diameter. Stipe more or less cylindrical, dirty white to brownish white with pink to carmine granulae concentrated on the upper two-thirds of stipe, finely granular, annulus absent, 35–60 mm long. Basidiospores elliptical, 0-septate, 9–13 × 4–6 μm, smooth, pale yellow.

Distribution: Nelson, Buller, Southland.; 1st Record: McNabb (1968).

Significance: Consistently associated with Nothofagus in widely separated localities (McNabb 1968).; Host(s): Nothofagus fusca, N. menziesii.

COLLECTIONS EXAMINED: Under (1) N. menziesii, Otago, Catlins, Puketiro Reserve, 29 Mar 1966, R.F.R. McN., (HOLOTYPE, PDD 25168); Tapanui, Black Gully, Mar 1966, R.F.R. McN., 25169; (2) N. menziesii and N. fusca. Nelson, Maruia, Jackson's Creek, Mar 1966, R.F.R. McN. and J. A. McRobb, 25170.

PILEUS: convex when young, becoming plano-convex to applanate at maturity, 5-9 cm diam., dry, finely felted to subtomentose, deep reddish brown, cinnamon brown or cocoa brown, occasionally light brown, sometimes irregularly creviced near margin when old; cuticle a trichodermium, composed of erect, branched, septate hyphae 5-8.5 µm. diam., terminal cells with irregularly thickened walls and brownish contents, becoming disorganised at maturity; margin entire, often extending beyond pores, sterile. HYMENOPHORE: tubes to 7mm long, excavated around apex of stipe or occasionally adnate, dull yellow brown at maturity; pores dull carmine, angular, 0.5-1 mm diam.; staining faint greenish blue where damaged. STIPE: 3.5-6 cm long, more or less equal, 1.5-2.5 cm diam., solid when young, often stuffed at maturity, dry, finely granular to furfuraceous by aggregation of caulocystidia, sordid white to brownish white, brownish basally, with pink to carmine granulae concentrated on upper two thirds of stipe; flesh sordid white to pallid yellow, becoming faintly greenish blue on exposure to air; annulus absent. SPORES: spore print not obtained; spores melleous, elliptic-subfusiform, broadly elliptical. or occasionally obovate, 9.7-13-(16) X 3.9-5.2-(6.5) µm, smooth. HYMENIUM: basidia hyaline, clavate, 23-32 X 9-11.5 µm, 4-spored, cystidia sparse, scattered, hyaline, thin-walled, subcylindrical to ventricose-rostrate, 35-48 X 6.2-9.5 µm. HYMENOPHORAL TRAMA: bilateral, of the Phylloporus subtype, containing oleiferous hyphae to 10 µm. diam.; clamp connections absent. CONTEXT OF PILEUS: sordid white to pallid yellow, becoming faintly bluish green on exposure to air. TASTE AND SMELL: not distinctive. CHEMICAL REACTIONS: KOH and NH4OH on pileus and context of pileus—no definite reaction.

HABITAT: Solitary, gregarious, or caespitose under Nothofagus.
