Descriptions
Panellus metuloideus G. Stev. 1964
[GS] Pileus 3 x 2.5 cm., fuscous, moist, smooth, spathulate with down-rolled margin. Gills decurrent, creamy, shallow, moderately crowded with some forking, margins becoming serrulate. Stipe 3 X 4 mm., brown above, cream below. Spores 7-8 X 4~4.5um, amyloid, thin-walled (Fig. 1/55, p. 10). Metuloids 70 x 20um, pseudo-amyloid, with or without encrusting crystals, thick-walled, very abundant on gill-faces. HABITAT : on fallen wood in Beilschmiedia tawa forest, Keith George Park, Wellington, 31.3.1949, Stevenson (type). The cylindric amyloid spores of this fungus point to the genus Panellus where it is treated, but the very abundant pseudo-amyloid metuloids also relate it to the genus Hohenbuehelia. [EH] A glance at the illustrations shows that this species clearly has to be transferred to Hohenbuehelia. [JC] No lamellulae observed. The gill edge is slightly serrulate. The cap surface is polished chestnut brown. With a cream tomentum near attachment and white rhizoids. This is much darker than all previous species examined. A section through pileipellis shows a hyaline surface gelatinised layer, followed by a dark brown layer, followed by the medial stratum, followed once again by a dark brown layer adjacent to the hymenium. The double brown lines are quite clear under a stereo. Gloeosphex cheilocystidia are relativley few and mostly without apical globules. Spores most certainly inamyloid, length=5.9–7.4µm (µ=6.6, σ=0.34), width=3.9–5.2µm (µ=4.5, σ=0.36), Q=1.3–1.7µm (µ=1.46, σ=0.11), n=27.

Pileus 3 x 2.5 cm., fuscous, moist, smooth, spathulate with down-rolled margin. Gills decurrent, creamy, shallow, moderately crowded with some forking, margins becoming serrulate. Stipe 3 x 4 mm, brown above, cream below. Spores 7-8 x 4-4.5 µm amyloid, thin-walled (Fig. 55). Metuloids 70 x 20 µm, pseudo-amyloid, with or without encrusting crystals, thick-walled, very abundant on gill-faces.

Pileus 3 x 2.5 cm, fuscus, humidus, laevis, spatulatus, margine deorsum involuto. Lamellae decurrentes, cremeae, haud altae, modice confertae, interdum furcatae, marginibus demum serrulatis. Stipes 3 x 4 mm, superne brunneus, inferne cremeus. Sporae 7-8 x 4-4.5 µm amyloideae, parietibus tenuibus. Metuloidea 70 x 20 µm, pseudo-amyloidea, crystallis plus minus incrustata, parietibus crassis, in lamellarum faciebus copiosissima.
The cylindric amyloid spores of this fungus point to the genus Panellus where it is treated, but the very abundant pseudo-amyloid metuloids also relate it to the genus Hohenbuehelia.
Typus: Stevenson 465.
