TWO NEW SPECIES OF POLYPOEACEAE. 301 Hymenial surface — Of the same color, becomes brownish in drying, pores small and angular, pore tubes in the bigger specimen 8 mm. long, context yellowish, soft, brittle and friable.

Margin — In dried ones involute.

Cystidia — None.

Spores — Hyaline, smooth, oval 4xG/*; some round, 6/* in diameter.

Mr. Lloyd remarks : " It belongs in section 39 of Stip. Polyp, pamphlet and is suggestive of Polyporus ovinus of Europe. The soft, friable flesh of the dried specimen is a feature not known to me in any similar species "

It has been named friabilis on account of its soft friable context. For this suggestion of name I am indebted to Mr. Lloyd.

Habitat — Growing in clusters in imbricate manner on dead trunk of Tamarind tree, collected from Nagbol, Hooghli Dist., in July, 1919.

Pileus — Sessile, arising as lateral outgrowths in imbricate manner from the dead stump, in the form of an arc of a circle, hard, about 3 cm. long, about 2 cm. broad, about 8 mm. thick, internally yellowish-brown.

Upper surface — Brown, distinctly hairy, brown hairs a bit coarse, and arranged in regular concentric zones on the upper surface.

Hymenial surface — Dark-brown, pores uniform, minute, brown, pore-tubes short, 2 mm. long, context a bit hard.

Margin — With a black outline.

Spores — Deep brown, round, diameter 9.09/^.

Setas — None.

Mr. Lloyd says : "I cannot place a name for it. It is in section close to Polystictus subcogener."
