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.
