Tylopilus formosus G. Stev. 1962 [1961]

K(m) 235256, Stevenson 968. Peter J did not photograph this type. The pileus is minutely squamulose and the pores are excavated near the stipe. Spores length=10.2–12.4µm (µ=11.5, σ=0.56), width=3.7–5.3µm (µ=4.3, σ=0.39), Q=2.2–3.2µm (µ=2.67, σ=0.23), n=21. The pileipellis structure may serve to distinguish the two closely related species which have been referred to T. formosus. The type resembles the version with an attenuated stipe apex, excavated pores around the stipe apex, and dark brown/black but not strong violaceous colours (my #2). That is supported by Stevenson's description which does not mention violaceous colours.

Tylopilus formosus G. Stev. 1962 [1961]

Type: Mycorrhizal Fungi; Description: Basidiomata pileate. Pileus chocolate brown to dark brownish black, 60–150 mm in diameter, convex to applanate, velutinate, dry; flesh white. Pore surface excavated around apex of stipe; tubes yellowish white becoming pale brownish orange at maturity, up to 16 mm long; pores concolorous with tubes, oval to irregularly angular, 0.5–1 mm in diameter. Stipe tapering towards the apex, concolorous with the pileus or slightly paler, finely granular, annulus absent, 50–110 mm long. Basidiospores elliptical, 0-septate, 10–14 × 4–6 μm, smooth, pale yellow. DISTRIBUTION: Auckland, Wellington, Nelson, Buller, Mid Canterbury.
Distribution: Auckland, Wellington, Nelson, Buller, Mid Canterbury.; 1st Record: McNabb (1968).
Significance: Field observations strongly suggest that the fungus is a mycorrhizal partner of the plants listed above (McNabb 1968).; Host(s): Kunzea ericoides, Leptospermum scoparium, Nothofagus fusca, N. menziesii, N. solandri var. solandri, N. solandri var. cliffortioides, N. truncata.

PILEUS: convex, plano-convex or applanate, 6-15 cm diam., dry, velutinate, occasionally almost subglabrous in areas at maturity, chocolate brown to dark brownish black, sometimes with deep purplish tints; cuticle a trichodermium, composed of erect, branched, septate hyphae 5.5-12 n diam.. Terminal cells acuminate or bluntly acuminate, with dark brown contents, often becoming disorganised at maturity, and terminal cells aggregated into tufts; margin entire, often extending beyond pores and incurved, sterile. HYMENOPHORE: tubes to 16mm long, excavated around apex of stipe, very occasionally adnate, ivory to fawn when young, becoming pallid brownish orange at maturity; pores concolorous with tubes or slightly darker at maturity, oval to irregularly angular, 0.5-1 mm diam.. STIPE: 5-11 cm long, tapering apically to 2 cm diam., expanded basally to 3.5 cm diam., solid or slightly stuffed at maturity, dry, finely granular to furfuraceous by aggregation of caulocystidia, occasionally faintly reticulate at extreme apex, concolorous with pileus or slightly paler apically, sometimes with deep purplish tints; flesh white; annulus absent. SPORES: spore print brownish orange with pink tints (between Sayal Brown and Wood Brown); spores pallid stramineous, elliptic-subfusiform to broadly elliptical, 9.8-14.2-(15) X 4-5.3 µm., smooth. HYMENIUM: basidia hyaline, clavate, 21-33 X 7.5-11.5 µm., 4-spored; cystidia numerous, crowded at tube mouths, hyaline or brownish, thin-walled, obclavate, lageniform or ventricose-rostrate, 37-67 X 10-16µm.. HYMENOPHORAL TRAMA: bilateral, of the Boletus subtype; clamp connections absent. CONTEXT OF PILEUS: white, unchanging on exposure to air. TASTE: extremely acrid and bitter. SMELL: not distinctive. CHEMICAL REACTIONS: KOH and NH4OH on pileus and context of pileus—no reaction.
HABITAT: Solitary, gregarious, or caespitose under native broadleaved trees and shrubs.
ILLUSTRATIONS: Stevenson, Kew Bull. 15: pl. 2, fig. 1, la. 1961.

The above description differs from that of Stevenson in that cystidia are numerous and distinct, the range in spore size is considerably greater, and the spore print is brownish orange. The unchanging, bitter tasting context which does not stain yellow with KOH indicates that Tylopilus formosus belongs in sect. Tylopilus as defined by Singer (1962).

Field observations strongly suggest that T. formosus is capable of forming mycorrhizal associations with both Nothofagus and Leptospermum.

Tylopilus formosus may be recognised by the velutinate, dark brownish-black pileus and stipe, pallid brownish-orange hymenophore, and white, bitter tasting context.

TYPE LOCALITY: Lake Rotoiti, Nelson, New Zealand.
