95. Pleurotus cinerascens del. (L., cinerascens, becoming asli-coloured or grey). 
— Laterally attached at the apex. Pilous up to Tin. (1.2 cm.), convex to copulate, 
dark greyish-black, hoary round the edge, -whitish and densely hoary when young. 
Gills radiating from an excentrie point, moderately close and numerous, many 
short ones at the periphery, sometimes showing slight venose buttresses, grey. 
Flesh dark coloured, subgelatinous. Spores 6 x 3.5 y; pilous clothed with cells 
and processes covered with lateral wart-like projections. South Australia — 
National Park, August, 1927, on trunk of living Eucalyptus viminalis Lab. 
A species evidently closely related to P. applicatiis and P. subapplicatus, but 
characterised more particularly by the cells on the pileus, a feature not 
apparently recorded in P. appUcatus, from which it also differs in the gills being 
moderately close and grey and in the slightly smaller spores. The shape of the 
spores also separates it from P. subapplicatus. 
B. SPORES PINK OR SALMON-COLOURED. RHODOSPORAE. 
(a) Pileus distinct and easily separable from the flesiiy stem. 
*With a volva at the base of the stem. 
VOLVARIA Fr. 
(L., volvarius, having a volva or sheath.) 
“Pileus fleshy, regular. Stem central. Volva membranaceous, free, sheathing. 
Gills free. Spores pink, elliptical or subglobose, smooth, continuous. Growing- 
on the ground or on wood. ’ ' — Rea. 
Voivaria corresponds with Amanita psix in the white-spored group. Three 
species at least are quite large, the caps being 2 to Tin. across, but others seem 
to be small and rare. The volva at the base of the stem is definite, there is no 
ring and the stem is readily separable from the cap. The only member of the 
genus we possess, P. gloiocephala, is not uncommon on waste land. It is said
