Descriptions
Pleurotus scabriusculus sensu Massee 1899 [1898]
According to Pegler (1965) the type of this species seems to be a well characterised species of the genus Pleurotus. The New Zealand material, however, is totally different. One collection (COLENSO b 973) represents a species of Scytinotus Karsten (see fig. 290 a), with allantoid spores, measuring about 6-7 X 2.5-3 µ. In the other collection (COLENSO 749) we found elliptical spores with a brownish, minutely warted membrane, 7-9 X 3-3.5 µ (see fig. 290 b), it being a Phialocybe Karsten.
Pleurotus scabriusculus sensu Massee 1899 [1898]
Entirely white. Pileus thin, sessile, horizontal, fan-shaped ,or semicircular, margin usually more or less lobed, narrowed behind into a very short stem-like point of attachment which is covered with spongy down, surface of pileus (more especially behind) rough with scattered minutely projecting points, not striate, 2-5 cm. broad and about the same long (from base to margin) ; gills rather narrow and crowded, radiating from the point of attachment; spores elliptical, 6-7 x 3-3.5 µ.
Dannevirke, New Zealand. Australia, Admiralty Islands.
On logs.
Often more or less imbricated. I find the spores to be elliptical, 6-7 x 3-3.5 µ, 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.

Notes
taxonomic status
N.Z. material is quite different from the Australian type, and comprises a Scytinotus sp. (Colenso b973) [FIG. 24-290a] and a Phialocybe sp. (Colenso 749) [FIG. 24-290b], fide Horak 1971b, p. 452, FIG. 24-290.
