Pleurotus bursaeformis (Berkeley) (11,16) = Hohenbuehelia bursaeformis (Berkeley) Reid, Kew Bull. 17: 304, 1963.

A detailed study of this polymorphic species which is widely distributed throughout the Pacific basin, will be published at a later date.

Pleurotus euphyllus Berkeley (9 D) = Hohenbuehelia bursaeformis (Berkeley) Reid. Type material: SINCLAIR 1860.

This is another synonym of the common New Zealand species H. bursaeformis (see there).

131. X ? Pleurotus guilfoylei Berkeley (8, 16)

There is no material from New Zealand, but examination of the type revealed the fact that Pl. guilfoylei must be considered a further synonym of Hohenbuehelia bursaeformis (Berkeley) Reid (see also Pegler, 1965).

Pleurotus sordulentus Berkeley and Broome (11,16,29) = Hohenbuehelia brusaeformis (Berkeley) Reid. Examined material: COLENSO b 1230

Pleurotus tasmanicus Berkeley (8,16) = Hohenbuehelia bursaeformis (Berkeley) Reid.

Because of the subglobose, spiny or warted spores and the short, fusoid and slightly thick-walled pleurocystidia this collection (COLENSO b 896) can be identified as H. bursaeformis. This collection has nothing in common with the type from Tasmania which is considered to be a synonym of Panellus diversipes (Berkeley) Pegler 1965.

Pileus almost sessile or narrowed behind into a very short lateral stem-like base, horizontal or the margin drooping, very convex; flesh thin, whitish, downy behind, becoming glabrous towards the margin, 2-5 cm. across; gills slightly decurrent, transversely streaked, pallid; spores dingy-white, subglobose, 6-7 µ, diameter.
New Zealand. Tasmania.
On dead bark.
Solitary, or more or less imbricated. Pileus sessile, horizontal, thin, entirely white, rather soft, almost or often quite even and glabrous, margin entire or slightly lobed, spreading, reniform or semicircular, 3-6 cm. broad; gills radiating from the point of attachment, rather broad and crowded, thin ; spores white, smooth, subglobose, 7-8 x 6 µ.
Dannevirke, Nelson, New Zealand.
On logs, &c.
Apparently a common species in New Zealand, having been sent on four different occasions by Colenso ; also sent from Nelson by Dall. This species may possibly have been described somewhere by Berkeley, but I have not been able to find the account. Distinguished by thin substance and entirely white colour. Pleurotus guilfoylei somewhat resembles the present species, but differs in having the pileus tomentose behind and the margin persistently incurved.
Dimidiate or imbricated. Pileus sessile, attached laterally, horizontal, reniform, or semiorbicular, entirely white, even, glabrous, margin incurved, sometimes lobed, tomentose or downy behind near the point of attachment, 2-6 cm. across; gills rather broad and crowded, thin, margin quite entire; spores narrowly elliptical, 7-8 x 3.5 µ.
Dannevirke, New Zealand. Australia.
On logs, &c.
Closely superficially resembling Pleurotus colerasoi, Berk., but sharply distinguished by the narrowly elliptical, spores, also other minor characters. A specimen of this species, now in Kew Herbarium, from Richmond River, Australia, was found growing " on the stem of a living Areca monostachya."
Pileus horizontal, sessile and attached by, the edge or having a short stem-like point of attachment springing from the posterior of the pileus, orbicular or somewhat reniform, dingy-white, at first slightly hairy or strigose; becoming glabrous with age, margin incurved, sometimes lobed, 3-6 cm. broad; gills radiating from the point of attachment, rather broad, thin, ventricose, whitish; spores subglobose, minutely but distinctly warted, 7-8 µ, diameter.
New Zealand. Queensland.
On wood.
Resembling Crepidotus mollis in habit and general appearance, but distinguished by the persistently white gills and spores. The warted spores stamp this species.
Pileus reniform or semicircular, horizontal, even, smooth, dingy-white or pallid, invested with a gelatinous stratum, plane, or often depressed, and the margin acute and prominent, 1.5-4 cm. broad, produced behind into a very short tomentose stem-like base, or sessile; flesh 3-4 mm. thick at the base, becoming thinner towards the margin, soft, white, flesh of stem or point of attachment dingy; gills radiating from the point of attachment, rather broad, not crowded, with numerous intermediate ones, dingy-white; spores globose, 4-5 µ diameter.
New Zealand. Tasmania, Australia.
On rotten wood.
Distinguished by the species having a gelatinous stratum on the pileus, and by the pallid or dirty-white colour of every part. The pileus is often depressed or concave, and the gills correspondingly convex at maturity.
Pileus 2-7 cm diam., sordid white with greenish tinge to pale ochraceous, orbicular to reniform, smooth to velvety; flesh concolorous, tough gelatinous at first, drying to papery texture. Gills adnexed, sordid white, deep, moderately crowded, rather thick at first but drying thin, margins somewhat irregular. Stipe up to 0.5 x 1 cm, lateral, pale ochraceous, finely fibrillose; or absent. Spores 8-11 x 6-9 µm, non-amyloid, thick-walled, with sharp or blunt spines (Fig. 48). Hymenophoral trama more or less regular of thin-walled hyphae up to 10 µm diam. Cystidia occasional on gill faces. Cuticle of loosely woven more or less regular thin-walled hyphae.
On fallen timber, Levin, 22.5.1949, Stevenson; Keith George Park, Wellington, 30.5.1949, Stevenson; Lake Rotoiti, Nelson, 8.7.1949, A. Crawford; Waikanae, 27.7.1958,M. Davidson.
The different collections show considerable variation in the thickness of the spore-wall and the sharpness and the length of the spines. Pleurotus guilfoylei Berk., P. colensoi Berk. and P. scabriusculus Berk., the types of which have been examined at Kew, all have very similar spiny spores. More collections and studies of the fresh material are needed. The cystidia figured by Mr. D. A. Reid are occasionally present on the gill-faces in Lloyd's material, which was collected at Waikaremoana by H. Hill (no date), and also in some of the writer's collections, but they are not a striking feature of the gills as they are in the following genus.
As Agaricus temulentus, Colenso b 751 Indicated by Horak (197ib) to lack all the essential features of the Bolbitiaceae. The basidiospores are 8-10 x 5-6 µm, kidney-shaped, smooth and honey-coloured in ammoniacal solutions. The cheilocystidia are diverticulate and pleurocystidia absent. There is controversy concerning the true identity of Ag. temulentus.  Thus material in Kew collected at Glamis, Scotland by the Rev. J. Stevenson is Agrocybe arvalis (Fr.) Singer, yet material identified by M. C. Cooke and cited by Orton (in Dennis, Orton Si Hora, 1960) is in fact a member of the Tricholomataceae (see also Reid & Austwick, 1963).
