deadly. It might easily be confused with Venenarius muscarius, 
for example. 
Hydrocybe caespitosa sp. nov. 
Clustered Hydrocybe 
Plate 1 13. Figure 2. X 1 
Pileus convex to obconic, depressed at the center, loosely or 
densely clustered, about 2-2.5 cm - broad and 1.5 cm. thick; sur- 
face dry, melleous, ornamented with brown, innate, pointed scales, 
which are denser on the disk ; context flavous, mild ; lamellae 
broad, ventricose, distant, sinuate-decurrent, stramineous to 
cremeous; spores ellipsoid, pointed at one end, smooth, hyaline 
granular, 7. 5-8.5 X 4-5 a 1 ; stipe equal or enlarged above, gla- 
brous, shining, citrinous, spongy within, 4-5 cm. long, 3-5 mm.

Type collected among moss in an open pasture east of Bronx 
Park, New York City, September 26, 1909, by W. A. Murrill. 
Also collected in the same field October 8, 1911, by W. A. Murrill 
and E. C. Volkert. Specimens have been sent me very recently 
by Professor Coker from Chapel Hill, North Carolina, collected 
by W. B. Cobb. According to Saccardo’s nomenclature, this 
species would be called Hygrophorus caespitosus.
