5. Chlorophyllum Mass. Kew Bull. 135. 1898 

 This genus was separated from Lepiota on the basis of the 

 green color of its fresh spores, with C. esculentum as its type and 

 C. M or gam and C. Molybdites as additional species. We now 

 know that these three names all refer to the same plant, which 

 ranges from Brazil northward through the United States. The 

 European species, Schulzeria Eyrei Mass., also has green spores, 

 but no annulus. 



The green color in the spores of Chlorophyllum seems to dis- 

 appear rather quickly on drying, leaving the spores pale-brown, 

 so that herbarium specimens are usually referable to the genus 

 Agaricus, although otherwise resembling Lepiota. In describing 

 Agaricus guadelupensis, Patouillard remarks that it is exactly 

 intermediate between Agaricus and Lepiota, the spores being too 

 pale for the former genus and too dark for the latter. 



A dozen or more of the Boletaceae, among them several of our 

 commonest species, have spores that are greenish or olivaceous 

 when fresh, fading to brownish on drying, but in none is the green 

 color so pronounced as in Chlorophyllum.

This very large and attractive species, found in pastures and 

 cultivated grounds, is of unusual interest on account of its green 

 spores. It is used for food in many places, but is poisonous to 

 some persons, though never fatal. It was first described from 

 Guiana by Meyer, and was known to Fries through Lund's col-
