characteristic odor; lamellae adnexed, white, close, narrow, in- 

 serted, ventricose ; spores ellipsoid, smooth, hyaline, 8-9 X 3-5-4 /j"- > 

 stipe hollow, cartilaginous, milk-white at the apex, polished and 

 slightly colored below, 3 cm. long, 2.5 mm. broad. 



Collected by Mr. E. C. Volkert, July 31, 191 1, on buried decayed 

 sticks, acorns, and grass roots under an oak tree on a lawn in 

 Bronxwood Park, New York City. This form is quite different 

 in appearance from that found so commonly in our woodlands, 

 but agrees well with plants collected in Kew Gardens, England, 

 and elsewhere in Europe in open places. The species is edible, 

 abundant, very variable, and very widely distributed. 



Mycena praedecurrens sp. nov. 



Decurrent-gilled Mycena 



Plate 68. Figure 4. X i 



Pileus conic to subturbinate when young, then umbonate, and 

 at length nearly plane, densely gregarious to, subcespitose, reach- 

 ing 1.5 cm. broad and nearly i cm. high; surface glabrous, very 

 slightly viscid when wet, avellaneous, with darker avellaneous 

 umbo ; margin straight, appressed, usually striate, often yellowish- 

 white; lamellae long-decurrent, distant, nearly plane, inserted, 

 entire, white with an ashy tint, acute at each end ; spores ovoid, 

 smooth, hyaline, 5X3-3-5/^; stipe enlarged at the apex, sub- 

 glabrous, gelatinous-white, avellaneous at the base, slightly viscid 

 when wet, stuffed, about 4 cm. long and 2 mm. thick. 



The type specimens here figured were collected by W. A. 

 Murrill in the Bronx, June 18, 191 1, on a mossy bank filled with 

 slender roots, in low deciduous woods. On account of its long- 

 decurrent gills, one might assign it at first sight to Omphalia, of 

 the type of Omphalia Austinii Peck, but it is not umbilicate. Its 

 nearest relative is probably Mycena vulgaris.

Pileus convex to subplane, gregarious to subcespitose, 2-4
