This beautiful species was collected in the island of St. Thomas 

 by Oersted, who made a colored drawing of it which may still be 

 seen at Copenhagen, but no trace of the fungus itself was discov- 

 ered either in Denmark or in Sweden. The pileus is represented 

 as dilute wine-colored, with a purple center, and the stipe is con- 

 colorous except at the apex, where it abruptly changes to white. 

 The general form of the plant is more like Lepiota than Melano- 

 leuca. 



3. Melanoleuca jamaicensis sp. nov. 



Pileus umbilicate, solitary, 2-3 cm. broad; surface glabrous, 

 latericious-fulvous ; lamellae sinuate with a decurrent tooth, lateri- 

 cious, broad, rather distant ; spores globose, smooth, hyaline, 3-4^ ; 

 stipe slender, cylindric, equal, glabrous, concolorous with the sur- 

 face of the pileus, 4 cm. long, 2.5 mm. thick, the apex much en- 

 larged, 5 mm. thick, stramineous, and tomentose. 



Type collected on the ground under tree-ferns at Morce's Gap, 

 Jamaica, 5,000 ft. elevation, December 29, 30, January 2, 1908-9, 

 W. A. & Edna L. Murrill J2c. The fresh plant has the appear- 

 ance of Clitocybe proximo, Boud. 



4. Melanoleuca subisabellina sp. nov. 



Pileus irregular, convex to infundibuliform, gregarious, 4-8 

 cm. broad ; surface glabrous, dull-colored, dingy-isabelline, mar- 

 gin undulate or slightly lobed, inflexed ; lamellae sinuate, straight, 

 narrow, rather close, white to dirty-brownish ; spores ellipsoid, 

 hyaline, 5 X 3-5 with minute, short prickles ; stipe curved, taper- 

 ing toward the base, glabrous, fleshy, white, 3 cm. long, 3-10 mm. 

 thick. 



Type collected on a waste heap of earth and vegetable refuse in 

 Castleton Gardens, Jamaica, December 14, 15, 1908, W. A. & 

 Edna L. Murrill 45. 



5. Melanoleuca jalapensis sp. nov. 



Pileus convex, much split at the margin, solitary, 4 cm. broad ; 

 surface dry, glabrous, shining, more or less radiate-rimose, the 

 castaneous cuticle remaining entire at the center, but almost dis- 

 appearing near the margin, where it persists in faint streaks or 

 patches ; context thin, white, sweet ; lamellae adnate with a slight 

 sinus, narrow, rather close, cremeous, pruinose under a lens ; 

 spores globose, smooth, hyaline, 5 /x ; stipe cylindric, equal, gla-
