COLLECTIONS EXAMINED: Under (1) L. ericoides and L. scoparium, Auckland, Kerikeri, Opito Bay, Apr 1966, G. B. Rawlings, 25264-5; (2) L. scoparium, Opito Bay, 16 May 1966, R.F.R. McN. (HOLOTYPE, PDD 25266).

PILEUS: convex when young, applanate at maturity, often with reflexed margins when old, 5-11.5 cm diam. dry, finely felted to subtomentose, dull yellow to greyish yellow; cuticle a poorly organised trichodermium when young, becoming disorganised at maturity and composed of interwoven, thin-walled, septate hyphae, terminal cells repent, oblique, or erect, 5-8 µm diam.; margin entire, incurved, extending beyond pores, slightly more tomentose than remainder of pileus. HYMENOPHORE: tubes to 7 mm long, adnate to subdecurrent, pallid yellow when young, becoming bright golden yellow at maturity; pores concolorous with tubes, often discoloured reddish brown in places, irregularly angular, 1-1.5 mm diam.; unchanging where damaged. STIPE: 3-5 cm long, more or less equal, 2-3.5 cm diam., solid, dry, subglabrous to finely subvelutinate from a close palisade of caulocystidia, occasionally faintly reticulate at extreme apex, pastel yellow or slightly darker; flesh pallid yellow to yellow; annulus absent. SPORES: spore print insufficient for accurate determination, but near olive brown; spores melleous, broadly elliptic-subfusiform, occasionally obovate, ll-13.8-(14.9) X 4.5-5.9-(6.9) µm, smooth. HYMENIUM: basidia hyaline, clavate, 35-49 X 9.5-11.5 µm, 4-spored; cystidia numerous, scattered, hyaline, thin-walled, ventricose-rostrate, 42-72 X 8.4-11.5 µm. HYMENOPHORAL TRAMA: bilateral of the Boletus subtype; clamp connections absent. CONTEXT OF PILEUS: pallid yellow to yellow, unchanging on exposure to air. TASTE: unpleasant, slightly acrid. SMELL: not distinctive. CHEMICAL REACTIONS: KOH on pileus—darkening; on context of pileus—reddish; NH4OH on pileus and context—no reaction.

HABITAT: Solitary or gregarious under Leptospermum.
