lections in Brazil. Berkeley assigned the name Pholiota Glaziovii 

 to specimens collected near Rio Janeiro, Brazil. Specimens col- 

 lected by Jenman in British Guiana were named Lepiota ochro- 

 spora, owing to the fact that the spores in dried specimens appeared 

 ochraceous by transmitted light. Other specimens collected at 

 the same time by Jenman in pastures near the coast received the 

 name of Chlorophyllum esculentum, because the gills were ob- 

 served to turn green at maturity and the plant was known to be 

 edible. Even in poorly preserved specimens, it is readily recog- 

 nized by its peculiar spores, which are ovoid, smooth, pale-brown 

 in herbarium material, apiculate, 7-9 X 5-6 /x, at times slightly 

 larger, especially in fresh specimens.

This is a very important tree parasite in temperate regions, and 

 is also much used for food. In the tropics, it is evidently not 

 thoroughly at home, having been found by our collectors only at 

 Mooretown, Jamaica, and at Jalapa, Mexico. For a description 

 and a colored illustration of this species, see Mycologia i : 2.
