Hohenbuehelia parsonsiae G. Stev. 1964

[GS] Pileus 3-6 X 2-4 cm., deep reddish brown, spathulate with down-rolled margin, somewhat striate at first, smooth; flesh concolorous. Gills deeply decurrent, fawn to ochraceous, deep, moderately crowded. Stipe 0-5 X 0-5 cm., lateral, concolorous, solid, fleshy, uniting in groups. Spores; 7 X 5um, non-amyloid, thin-walled. Metuloids 50 X 15um, pseudo-amyloid, very thick walled, encrusted with crystals, very abundant on gill faces (Fig. 1/49, p . 10). Cuticle subregular, with occasional thick-walled hyphae with sharp pointed hyphal endings. HABITAT: in humus soil or on fallen wood, Levin, 25.7.1948, G. Parsons in Stevenson (type); Otari, 7.6.1958, Stevenson. [EH] = Hohenbuehelia petaloides (Fries) Schulzer. This species may be introduced as it is frequently found on ruderal places or in lawns. [JAC] Macromorphology does suggest H. petalodes/metuloidea, e.g. pileus (material fragmented) is polished chestbut brown. With rhizoids. GS drawing has this clearly as spathulate. Spathulate/fan-shaped is not a good character according to sequences. Pileipellis section with single dark band. Pilocystidia subuate, thick-walled. Consistent with H. metuloidea and provides an earleir name. Gloesphex cystidia not observed. Spores from lamella squash length=6.4–7.5µm (µ=7.0, σ=0.35), width=4.0–5.4µm (µ=4.6, σ=0.33), Q=1.3–1.7µm (µ=1.53, σ=0.11), n=20. Spores on cap minutely roughened? Must be something else.

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.

Panellus metuloideus Stevenson (29 D) Fig. 16 = Hohenbuehelia metuloidea (Stevenson) comb. nov. (Basionym: P. metuloideus Stevenson, Kew Bull. 19: 27, 1964)

A glance at the illustrations shows that this species clearly has to be transferred to Hohenbuehelia.

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.
On fallen wood in Beilschmiedia tawa forest, Keith George Park, Wellington, 31.3.1949) Stevenson (type).
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.
