 Islands. 



Often more or less imbricated. I find the spores to be 

 elliptical, 6-7 x 3-3-5 /x, in the type specimen from Australia 

 and in Colenso's New Zealand specimens. Distinguished 

 among the entirely white species by the scabrid or minutely 

 rough surface of the pileus.

 Sacc, Syll. v., no. 1487 ; Cke., Austr. Fung., p. 35. 



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 jx diameter.

74. Pleurotus guilfoylei, Berk., Journ. Linn. Soc, v., xiii., 

 p. 158; Austr. Fung., p. 33; Sacc, Syll. v., no. 1409. 



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 /x. 



On logs, &c. Dannevirke, New Zealand. Australia. 



Closely superficially resembling Pleurotus colensoi, Berk., 

 but sharply distingviished by the narrowly elliptical spores, 

 also other minor characters. A specimen of this species, now 

 in Kew Herbarium, from Eichmond Eiver, Australia, was 

 found growing " on the stem of a living Areca mono s tacky a." 



75. Pleurotus colensoi, Berk., in Herb. 



Solitary, or more or less imbricated. Pileus sessile, hori- 

 zontal, 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 /x. 



On logs, &c. Dannevirke, Nelson, New Zealand. 



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 de- 

 scribed somewhere by Berkeley, but I have not been able to
