Laterally attached at. the apex. Pileus up to 1/2 in. (1.2 cm.) in diameter, convex to cupulate, dark greyish-black, hoary round the edge, whitish and densely hoary when young. Gills radiating from an excentric point, moderately close and numerous, many short ones at the periphery, sometimes showing slight venose buttresses, grey. Flesh dark coloured, sub- gelatinous. Spores 6X3.5 um; pileus clothed with cells and processes covered with lateral wart-like projections. S.A.—National Park, August, 1927. on trunk of living Eucalyptus viriminalis, A species evidently closely related to P. applicatus and P. subapplicatus, but characterised more particularly by the cells on the pileus, a feature not apparently recorded in P. applicatus, from which it also differs in the gills being moderately close and grey and in the slightly smaller spores. The shape of the .spores separates it from P. subapplicatus.
