Article: Stevenson, G. (1964). The Agaricales of New Zealand: V. Kew Bulletin 19(1): 1-59.
Description: Pileus 2-4 x 1.5-3 cm, dark greyish brown, fan-shaped to reniform becoming somewhat lobed, margin strongly down-rolled at first, densely fibrillose, sessile; flesh thin, white, tough. Gills decurrent to the thickened point of attachment, creamy to ochraceous, shallow, moderately thick, very crowded. Spores 6 x 3-3.5µm, non-amyloid. Metuloids very thick-walled, pointed, with or without crystals, very abundant (Fig. 54), Cuticle of loosely woven thin-walled hyphae 4 -5 µm diam., with clamp connections; tomentum of unbranched similar hyphae containing pigment.
Habitat: On fallen dead Nothofagus, Rotoiti, Nelson, 6.6.1955, Stevenson (type).
Notes: This species and the previously described one seem closely related but distinct, and it is presumed that the host range of each is restricted.

Article: Stevenson, G. (1964). The Agaricales of New Zealand: V. Kew Bulletin 19(1): 1-59.
Description: Pileus 1-2 x 1-1.5 cm, buff to sordid, finely fibrillose, fan-shaped, sessile. Gills decurrent to point of attachment, creamy white, shallow, crowded. Spores 7 x 3 µm, non-amyloid, thin-walled. Metuloids 80-90 x 15-20 µm, pseudo-amyloid, very thick-walled, encrusted with crystals, very abundant on gill-faces (Fig. 53). Cuticle of loosely woven hyphae with clamp connections, covered by tufts of parallel thin-walled hyphae 3-8 µm diam., with conspicuous clamp connections.
Habitat: On fallen rotten wood, Levin, 27.10.1947, Stevenson (type).

Article: Massee, G.E. (1899) [1898]. The fungus flora of New Zealand. Transactions and Proceedings of the New Zealand Institute 31: 282–349 Wellington:.
Description: Pileus at first resupinate, sessile, soon distinctly reflexed and becoming horizontal, obovate or reniform, downy, rarely almost glabrous, rugulose when dry, due to contraction of the cuticle, usually blackish-blue, rarely brownish; 2.5-5 cm long, up to 2.5 cm broad; flesh soft, upper stratum (pellicle) slightly gelatinous, up to 4mm thick, blackish-brown; lower layer (or flesh proper) thin and whitish; gills at first radiating from a point inside the margin, then converging towards the base, broad, whitish, at length tinged with yellow; spores 7-8 x 5 µ.
Habitat: On rotten trunks.
Distribution: Dannevirke, New Zealand. Australia, Central Africa, Europe, United States.
Notes: Sessile, gregarious, somewhat imbricated. Smell pleasant. Distinguished by the dusky colour of the pileus and by the dark-coloured gelatinous cortical layer.

Notes: Of the three collections in Kew, one belongs to Henzicybe Karsten (COLENSO b 534), while the two remaining collections (COLENSO b 329, b 975) are conspecific with Hohenbuehelia nothofaginea Stevenson.

Notes: Pleurotus serotinus (Fries) (6) Fig. 25 = Hohenbuehelia nothofaginea Stevenson
After studying this collection (COLENSO b 72) we cannot see any differences between it and H. nothofaginea, a ubiquous fungus in the beech forests of New Zealand.

Article: Massee, G.E. (1899) [1898]. The fungus flora of New Zealand. Transactions and Proceedings of the New Zealand Institute 31: 282–349 Wellington:.
Description: Pileus rather fleshy, at first resupinate, then expanded and horizontal, reniform or semicircular, glabrous, covered with a thin viscid pellicle, reddish-brown, grey, or umber, sessile or prolonged, behind into a short stem-like base; 1.5-3 cm. across; gills radiating from the point of attachment of the pileus to the matrix, rather broad, crowded, yellowish ; spores subglobose, 5-6 p, diameter.
Habitat: On rotten wood, stumps, &c.
Distribution: Dannevirke, New Zealand. Europe, United States, Chili.
Notes: Usually caespitose and imbricated.

Notes: Fig. 2 = Hohenbuehelia aff. nothofaginea Stevenson
The size and dimensions of the microscopical characters found in this collection (COLENSO 1007) are very similar to those of H. nothofaginea Stevenson.
