and one would expect it to occur there at high elevations. There 

 are, however, certain tropical species with which it might be con- 

 fused by the superficial observer. 



3. Hypholoma tuberculatum Pat. Bull. Soc. Myc. Fr. 15: 



196. 1899 



Described from specimens collected by Duss at Basse-Terre. 

 Guadeloupe, on old trunks of Hura crepitans. Known only from 

 the type locality. Morgan transferred this species to Stropharia 

 because of its persistent annulus, while Patouillard placed it 

 in Hypholoma probably because of its close relationship to H. 

 fasciculare. 



4. Hypholoma flavovirens sp. nov. 



Pileus convex, not umbonate, densely cespitose, 2-3 cm. broad 

 and about 5 mm. high ; surface dry, glabrous, faintly rugose, pale- 

 flavovirens; lamellate adnate, arcuate, narrow, crowded, flavo- 

 virens, becoming pale-purplish-brown at maturity ; spores ellipsoid 

 or elongate-ovoid, smooth, usually 2-guttulate, very pale purplish- 

 brown under the microscope, 7X 4/a; stipe equal, smooth, 

 glabrous, pale-flavovirens, slightly ochraceous below, 3-4 cm. long, 

 2-2.5 mm. thick; veil slight, appendiculate, evanescent. 



Type collected on decayed logs and stumps at Cinchona, 

 Jamaica, 1,500 m. elevation, December 25, 1908, W. A. & Edna 

 L. Murrill 553. Also collected at Cinchona, Jamaica, W. A. & 

 Edna L. Murrill 534; on a log on Sir John Peak, Jamaica, W. A. 

 Murrill 782; on a rotten stump at Mooretown, Jamaica, F. S. 

 Earle 559; and on a stump at Jalapa, Mexico, W. A. & Edna 

 L. Murrill 72, 74. This species occurs in abundance at Cinchona 

 on dead logs and stumps in the vicinity of the laboratory. It 

 closely resembles Psilocybe subviridis and also suggests Hypho- 

 loma fasciculare. 



9. Pilosace (Fries) Pat. Hymen. Eur. 122. 1887 



Agaricus § Pilosace Fries, Nova Acta Soc. Sci. Upsal. III. 1 : 

 25. 1851. 



This genus has a fleshy stipe and purplish-brown spores, but 

 differs from Agaricus in being without a veil. There are very
