22 SCIENTIFIC AND APPLIED PHARMACOGNOSY 



LEPIOTA MORGANI. Green Gill. Cap fleshy, globose when young, 

 on expansion plane or slightly depressed, not umbonate, white with 

 a yellowish or brownish cuticle, which breaks up into scales except 

 in the center; flesh white, changing to reddish or yellowish on being 

 cut or bruised; gills close, lanceolate, remote, white becoming green; 

 stem firm, smooth, hollow, subbulbous, tapering upward, white with 

 brownish tinge; ring large, movable. 



Cap 12.5 to 22.5 or even 30 cm. broad; stem 15 to 22.5 cm. long, 

 8 to 16 mm. thick. 



Great care should be taken to avoid this species. Many instances 

 of poisoning are well substantiated, and extreme inconvenience and 

 serious illness have resulted from eating very small pieces of the 

 uncooked mushroom. The gills are slow in assuming the green tinge 

 characteristic of this species, but after being allowed to remain in 

 ordinary room temperature the color is quite noticeable. This 

 fungus occurs mostly on grassy places, such as lawns and parks, dur- 

 ing the summer months, frequently forming large " fairy rings." 



Clitocybe Illudens. Cap fleshy, convex or expanded, then 

 depressed, sometimes with a small umbo, saffron yellow, in age 

 becoming sordid or brownish; gills broad, distant, unequally decur- 

 rent; stem solid, firm, smooth and tapering toward the base, ascend- 

 ing, curved, rarely erect, color same as cap. 



Cap 10 to 15 cm. broad; stem 12.5 to 20 cm. long. 



This is a very striking fungus both on account of its color and the 

 large clumps it forms about stumps or decaying trees. It is often 

 irregular in form, from the crowded habit of growth. On account of 

 the phosphorescence which renders it conspicuous at night, it is 

 commonly known as the jack-o'-lantern. While not considered 

 poisonous, it produces illness and is to be carefully avoided. It 

 may be found from August to October. 



Lactarius Fumosus. Cap convex, plane or slightly depressed, 

 snuff brown or coffee-colored, dry glabrous or pruinose, very smooth, 

 margin entire or sometimes wavy; flesh white, changing to reddish 

 when wounded; gills subdistant, adnate, or slightly decurrent, white 

 then yellow, becoming pinkish or salmon where bruised ; stem nearly, 

 equal or slightly tapering downward, stuffed, then hollow, colored 

 like the cap. 



Cap 5 to 7.5 cm. broad; stem 4 to 6 cm. long, about 12 mm. thick. 



This species varies considerably in size, color, and closeness of 

 the gills. The distinguishing features for field identification are the 

 coffee-colored cap and the changeable color of the flesh and gills. 

 Its use should be strictly avoided, as it closely resembles Lactarius
