text mild ; lamellae deciirrent, broad, distant, strongly interveined, 

 inserted, white, entire ; spores large, oblong, smooth, hyaline, lo- 

 i2X4-6/>t; stipe increasing upward, tough, minutely longitudi- 

 nally striate, pruinose to glabrous, grayish-avellaneous below, 

 paler above, 1-3 cm. long, 2 mm. thick. 



Type collected on a dead deciduous log in the New York Botan- 

 ical Garden, August 28, 191 1, by IV. A. Murrill. Found com- 

 monly on dead wood in moist or shaded situations about New 

 York City during late summer and autumn. Professor Penning- 

 ton, who assigns it to the same group with M. V aillantii Fries, col- 

 lected it at Washington, D. C, last August on several occasions 

 and noted considerable variation in it. Marasniius viticola Berk. 

 & Curt, is a closely related species occurring in the eastern United 

 States farther south.

Sporophores solitary or clustered, 10-12 cm. high; stipe white, 

 divided above into six, usually, but sometimes five or seven, nar- 

 rowly lanceolate hollow arms ; arms incurved above, with pale 

 flesh-colored backs traversed their entire length by a shallow fur- 

 row ; cavity of the stipe nearly closed at the base of the arms by 

 a diaphragm through which there is an opening upward into a 

 closed chamber with a dome-shaped wall ; gleba supported on the 

 dome and closely embraced by the arms ; spores oblong, hyaline, 

 3-4 X 1.5 ft, borne on cross-septate basidia constricted at the septa. 



This interesting and remarkable species was first described as 

 above by Mr. E. A. Burt from New York specimens, and was 

 later collected in Massachusetts, growing in both states in gardens 

 or cultivated fields. It was brought to my attention in May, 1911, 

 by Dr. F. M. Bauer, Superintendent of the Metropolitan Hospital 

 on Blackwell's Island in this city, who found quantities of it in 

 his mushroom beds and supplied me with a number of specimens 

 for colored drawings and photographs. 



The odor of the mature sporophore is very vile and penetrating 

 at close range, somewhat resembling that of fresh guano, but it is 

 not pervading like that of Dictyophora diiplicata, for example, and
