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 dia- 

 meter. 



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. 



2. Polystictus Sarbadhikarii, sp. nov. 



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.
