Fig. 24 



H. cinerascens. 



Hyphae, spore x 640. 



Fructification effused, byssoid, membranaceous, separable, 

 drab-gray, the margin the same color or whitish ; in structure 



200-350/1 thick, with the hyphae hyaline un- 

 der the microscope, thin-walled, nodose- 

 septate, loosely interwoven ; basidia with 4 

 sterigmata; spores drab-gray in a spore 

 collection, globose, echinulate, the body 

 41/4-5 ly-oM in diameter. 



Fructification 2-3 cm, long, l-l^A cm. 

 broad. 



On bark of Alnus. New Hampshire and 

 Montana. September. 



This species is distinguished from H. 

 epigaeus by drab-gray color, fructification 

 easily separable from substratum, occurrence on wood, small- 

 er and echinulate spores, and hyphae of smaller diameter and 

 more uniformly interwoven. 



Specimens examined: 

 Finland: Mustiala, P. A. Karsten. 

 New Hampshire : Chocorua, W. G. Farlow, 17. 

 Montana : Missoula, J. R. Weir, 440 (in 

 Mo. Bot. Gard. Herb., 22144). 



25. H. peniophoroides Burt, n. sp. 



Type: in Burt Herb, and in N. Y. 

 Bot. Gard. Herb. 



Fructification long and widely ef- 

 fused, coriaceous, compact, adnate, gla- 

 brous, pinkish buff, the margin entire, 

 determinate; in structure 300-400/^ 

 thick, stratose, composed of fine inter- 

 woven hyphae and numerous cystidia; 

 hyphae concolorous with the fructifica- 

 tion, ly^/A in diameter, not nodose-sep- 

 tate, densely interwoven, dichotomously 

 branched, and with antler-shaped hyphal 

 branches especially noticeable at the 

 surface of the hjTuenium ; cystidia very 

 numerous in all regions of fructification, cylindric, acute, 36-
