174 JOUEISTAL OF THE MiTCHELL SoCIETY [MaVcJl 



larger and rougher, of which I sent you photos and specimens. My 

 feeling is that while your plant can be referred to Banker's species 

 my larger one cannot. It does not dry to a translucent mass, the flesh 

 is far from being 'less than 1 mm. thick when dry,' and the stipe in 

 my plants is always a peculiar green at the base." 



8. Hydnum Murrilli (Banker) 



This species is represented at the l^ew York Botanical Garden by 

 an ample type collection (Murrill and House JSTo. 397) from the 

 mountains of ISTorth Carolina. I have examined the plants and find 

 them very near H. Uiidenvoodii with the same short, fine teeth ; but 

 most of the plants are more infundibuliform than is our H. Under- 

 ivoodii and the color of the dried plant is more yellowish. Further 

 comparison in the fresh state are needed. The original description 

 by Banker follows (Mycologia 5 :15. 1913) : 



"Hymenophore terrestrial, mesopodous, medium to large size, red- 

 dish-bro"WTi ; pileus expanded to infundibuliform, subrotund to irregu- 

 lar, 5-10 cm. wide, 1-2 mm. thick when dried ; surface roughened with 

 fine floccose scales, coarsest toward center, 1-2 mm. wide, ends up- 

 turned, about as long as wide, subzonately arranged, dark-reddish 

 brown on scales, lighter between ; margin thin, fertile, repand, finely 

 lobed or crenate, pallid; substance fleshy, pale-bro\vn to whitish, 

 drying thin, but somewhat tough and flexible; stem subcentral, 

 strongly inclined, tapering gradually and then abruptly to the base, 

 reddish-brown above, concolorous with pileus, paler below but be- 

 coming blackish at the base, scabrous roughened nearly to the base, 

 apparently hollow or stuffed, 4-6 cm. long, 1-2 cm. wide ; teeth small, 

 slender, terete, tapering, acute, crowded, decurrent nearly to the base, 

 reddish-brown, white tipped, 1.5 mm. or less long in dried plant, 

 0.15-0.25 mm. wide, 9-12 to a square mm. ; spores subgiobose, tuber- 

 culate, tubercles not prominent, pale-brownish, 6-7/* wide; basidia 

 prominent, irregular, clavate, 8-1 0/* wide ; sterigmata conical, curved, 

 horn-shaped, 3-4/>i long ; hyphae of trama hyaline, smooth, thin-walled, 

 collapsing when dried, recovering in KOH, subparallel but partly 

 separable in KOH, septate, without clamp-connections, segments
