to fall away, each one leaving a small pale spot or dot on the peridium 

 similar to those left by the falling of the warts from the peridium of 

 Lycoperdon gemmatum. Scleroderma verrucosum is said to be very 

 variable in size and color and in the degree of roughness of the exterior. 

 Its warts are described as persistent and adnate. Authors do not agree 

 in their description of the spores, one describing them as minute and 

 another saying that they are larger than those of any other species of 

 this genus. But in no description do I find any reference to the decidu- 

 ous character of the scales and the consequent dotting of the surface of 

 the peridium which is shown by our specimens. For this reason it has 

 seemed best to separate our plant as a variety worthy of recognition. 

 Possibly a more complete knowledge of it may show it to be worthy 

 even of specific distinction. Peck. 



All North American species of this genus, so far as known at present, 

 are edible. Care should be taken however to pare them well; to see 

 that the specimens are not wilted; to cut away the bases, and to cook 

 them thoroughly. 



Agaricus Morgani Pk. Since the remarks concerning this species 

 on pages 730 and 731 were set in type, Mr. O. E. Lansing, Jr. (who 

 collected, in 1902, the material which I then photographed and which 

 now forms the upper half of Plate Vila.) reports that: At about 6 p. 

 m. he ate a bit, about the size of a silver quarter, of one of the plants 

 photographed. In about two hours he was attacked with numbness of 

 the legs, faintness, burning in the throat and nausea; followed soon by 

 excessive vomiting and purging which continued at intervals until 4 a. 

 m. accompanied by great fear of death. Lassitude and weakness super- 

 vened but he was able to go about his duties that morning, and no fur- 

 ther unpleasant effects followed so far as he now remembers. 



In both the case of Mr. Lansing and that of Mrs. Clementson (page 

 730) the poisoning resulted from eating a small piece of the raw plant. 

 It is possible that those who have found the species inocuous ate the 

 cooked plant only. However, the species is one that should be carefully 

 diagnosed, well separated in the mind from A. procerus, and its collec- 

 tion as a food rigidly avoided. Millspaugh.
