8 46 THE AGARICACEAE OP MICHIGAN 



raw (?) L. morgani, mistaken for L. procera and eaten in very 

 small amount, presenting all symptoms above recorded but with 

 the addition of temporary blindness. Warren (Port Huron) records 

 that in a family of live who ate it two girls were made ill. Symptoms 

 came on early the next morning — seven hours after eating — and 

 were "almost as bad as from Gyromitra poisoning as it is known 

 in Port Huron. " 



THE GENUS TRICHOLOMA 



In this genus Mcllvaine agrees to label T. saponaceum and T. sul- 

 fa renin as inedible on account of taste. I had for years regarded the 

 entire genus as safe, but in August, 1908, we had a group of seven 

 rases of rather violent poisoning from an innocent-appearing Trich- 

 oloma. Good specimens were at once sent to Atkinson who de- 

 scribed them as a new species which he named Tricholoma venen- 

 ata in. This agaric has not been found again nor further tested. Of 

 the lot eaten many were badly infested by insects when examined 

 two days later. The symptoms came on one hour after supper and 

 consisted of vomiting, sometimes bloody, retching and considerable 

 prostration in three individuals. All recovered. Surprises like 

 this will continue to occur as long as fungi are eaten. It may be 

 years after some varieties of poisoning occur before the etiology is 

 satisfactorily settled: whether due to a new deleterious species; a 

 known inedible variety not recognized by the consumer; a personal 

 physiologic sensitiveness of the individual; decayed fungi of good 

 species or some infested by acrid insects; the rare presence of a 

 minor toxin in some generally-esteemed edible variety; or simple 

 acute indigestion— perhaps due to gluttony. The observer should 

 endeavor to fix positively the responsibility on the one real cause. 



THE GENUS C LIT OCT BE 



Like Lepiota, this large genus has for years been credited with 

 but one deleterious species. Within a few years two others have 

 been added. All three show muscarin symptoms in variety. 



Glitocybe illudens, known as the "Jack o' Lantern" 'because 

 of its phosphorescent glow, or the "Deceiving Glitocybe," is mis- 

 taken every year, in Detroit, by our foreign residents for Ann il- 

 ia ria mellea or for the European Chanterelle. And on such annual 

 fall occasions it holds high carnival and breaks into the newspapers. 

 The attending physician has a busy night or a few busv hours—
