218 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Wisconsin: Lake Geneva, E. T. € S. A. Harper, 950. 
Montana: Evaro, J. R. Weir, 436, 438 (in Mo. Dot. Gard. 
Herb. 19515 and 19597 respectively). 
Bahama Islands: 4. E. Wight (in Farlow Herb.). 
8. H. spiniferus Burt, n. sp. 
Type: in Farlow Herb. and in Burt Herb. 
Fructification effused, membranaceous, separable, tomen- 
tose, varying from sepia to fuscous; in structure about 1000. 
thick, with the hyphae loosely interwoven, 
nodose-septate, thick-walled, concolorous 
with the fructifieation but darker near the 
substratum and spinulose, the paler hy- 
phae rough-walled or even, body of largest 
I hyphae 4—5z# in diameter, the spines about 
piniferus la long, colored like the dark wall; basidia 
with 4 sterigmata; spores concolorous, 
globose, sometimes flattened on one side, echinulate, the body 
6-8, in diameter, or 6 X 414-6n. 
Fructifications about 5 em. long, 3 em. broad. 
On rotten wood. New Hampshire and Massachusetts. Au- 
gust. Rare. 
H. spiniferus is so similar to H. spongiosus in habit and 
coloration that it can be separated from the latter only by 
the distinctly spiny-walled and rough-walled hyphae of the 
former species. This character is as marked as in the capil- 
litium of some Myxomycetes. The New Hampshire collec- 
tions which I have included under H. spiniferus have rough- 
walled hyphae and no spines. 
Specimens examined: 
New Hampshire: Chocorua, W. G. Farlow, 11, and an un- 
numbered specimen collected in 1904. 
Massachusetts: Magnolia, W. G. Farlow, type.
