- 194. Hydnum (Resupinatum) Murraii. 2?.<fcC— Subiculum mem- 

 branous, thin, white ; prickles scattered, subulate, acute ; of a 

 pinkish ochre. No. 5707. New Eng., Murray. 



On very rotten wood. Subiculum, spreading widely, very thin, 

 membranaceous, slightly byssoid and pulverulent; prickles scat- 

 tered, of a reddish tint, subulate, smooth. 



This species, perhaps, should come next to II. Cookei. It is, 

 however, very difficult to say what is the colour of the prickles 

 when fresh.

 cis intertextum hie illic fibrillis repentibus ; aculeis verrucoeformi- 

 bus brevibus apice subciliatis. No. 4368. Penns., Michener. 



Entirely resupinate ; subiculum composed of interwoven flocci, 

 which here and there send out creeping threads ; aculei verruci- 

 form, the tips sometimes minutely ciliated. This species ap- 

 proaches Kneiffia.

 libus. No. 6093. 



Subiculum as in the last, but the hymenium totally different ; 

 prickles slender, waxy, subulate or nearly cylindrical, almost rufous 

 when dry.
