Hohenbuehelia brunnea G. Stev. 1964

[GS] Pileus 1-2 cm. diam., fuscous, paler at margin, orbicular with margin exceeding gills, velvety fibrillose; laterally attached. Gills decurrent to point of attachment, ochraceous yellow, thick, shallow, very crowded. Spores 7 X 3-3.5um, non-amyloid. Metuloids 40 X 12um, pseudo-amyloid encrusted with crystals, extremely thick-walled, very numerous (Fig. 1/50, p. 10). Cuticle of loosely woven, more or less parallel hyphae with clamp connections, up to 5um diam., superficial hyphae dark coloured and some irregularly thickened. HABITAT: on fallen twigs, Otari, 29.7.1948, Stevenson (type). [JC] Pileipellis relatively smooth compared to previous types which all had at last some cap area with a dense tomentum. Gills not as crowded as H. podocarpinea. The pileipellis is thin, and with brown setose elements like some of my petalodes. Some of these crystal encrusted, but easily lost. Surface hyphae with brown zebroid encrustation. Gloeosphex cheilocystidia relatively few. Spores length=6.0–8.2µm (µ=7.1, σ=0.58), width=3.1–4.1µm (µ=3.6, σ=0.27), Q=1.7–2.4µm (µ=2.00, σ=0.23), n=22
[GS] Pileus up to 5 x 4.5 cm., slate grey becoming tinged brown, orbicular becoming lobed, margin at first down-rolled becoming finally upturned, velvety, sessile; flesh firm, white. Gills decurrent to point of attachment, creamy white developing some ochre tints, rather thin, very crowded, dense metuloids appearing like fine white hairs. Spores 7-8 x 4um, non-amyloid, thin-walled. Metuloids up to 50 x 15um, pseudo-amyloid, very abundant, very thick-walled, pointed, with or without encrusting crystals (Fig. 1/5I, p. 10). Cuticle of loosely woven semi-gelatinized hyphae with conspicuous clamp connections, with a few irregularly thickened hyphal endings. HABITATo:n standing dead Podocarpus spicatus, Butterfly, 22.5.1949, Stevenson (type). [JC] Stevenson implied this is nearly the same as H. nothofaginea differeing in host. The dried material of this has a darker brown cap than H. nothofaginea and much more orange gills,. Some caps are smooth, others finely dark brown velvety, and some with a pale tomentum like H. nothofaginea and trstis. This is a substantial collection, and the individual fruitbodies are relatively large. No sign of basal rhizoids. Pileipellis tissue appears to be less gelatinised than either nothofaginea or tristis but is separable and has identical encrusted brown hyphae to nothofaginea, and a few thick walled dark brown pilocystidia (and a few hyaline). No pilo gloeosphex cystidia seen. The coarse and fine tomentum have the same micro structure. A number of the fruitbodies are infested with thick-walled minutely spiny spores of something else. Spoeres length=6.7–8.2µm (µ=7.2, σ=0.42), width=3.2–4.4µm (µ=3.7, σ=0.29), Q=1.7–2.2µm (µ=1.93, σ=0.15), n=20
