 spores are not altogether hyaline.

This very beautiful species occurs occasionally at several points 

 in our tropics, from sea-level up to 2,000 ft., and more frequently 

 in the United States, at various elevations, the spores as well as 

 the sporophore showing considerable variation. It also very 

 probably ranges southward into South America under forms rep- 

 resented by L. carminca Pat. and L. erythrella Speg. L. pur- 

 pureoco-nia Atkinson seems hardly sufficiently distinct. I am 

 indebted to Dr. Peck for the determination of specimens from 

 Louisiana.

19. Lepiota abruptibulba sp. nov. 



Pileus fleshy, rather thin, 6-7 cm. broad, hemispheric to sub- 

 expanded, at first umbonate, at length obtuse ; surface rich reddish- 

 brown, the cuticle breaking into minute, floccose-granular scales, 

 not striate, darker on the umbo; lamellae white, free, crowded, 

 unequal, rather broad ; spores subglobose to ovoid, smooth, hya- 

 line, tinged with brown, 5-5.5 X 4^', stipe cylindric, subglabrous, 

 tinged with reddish-brown, hollow, 7 cm. long, 6 mm. thick, the 

 base swollen into an abrupt, flattened bulb; annulus large, per- 

 sistent, superior, movable. 



Type collected on the ground in a banana field near Santiago 

 de las Vegas, Cuba, June 18, 1904, F. S. Earle 94. Also collected 

 in the same locality in June and September, F. S. Earle 67, 167 ; 

 and in thickets near Candelaria, Cuba, F. S. Earle 209. The 

 description is mainly drawn from Professor Earle's excellent 

 field notes.
