1922] The Laccarias and Clitocybes of North Carolina 109 



Stem long, solid and elastic, bent, tapering downward, eblor of 

 cap. 



Spores (of No. 183) white, sub-globose, smooth, 4-4.6;a thick. 



A large and very striking species growing in densely cespitose 

 clusters from the bases of stumps of deciduous trees or from roots 

 near the surface of the ground; not rare in September and October. 

 It was first described by Schweinitz from this State. The entire plant 

 is brightly colored and may be seen from a long distance. It is 

 poisonous to most people though not classed among the deadly species. 

 It is a severe emetic and may also cause intestinal derangement. For 

 cases in detail see Fischer in Kauffman's Agarics of Michigan, p. 486. 

 The gills exhibit a marked phosphorescence which may be easily 

 shown by looking at the plants in a dark room.

 Agaricus multiformis Schaeff., plate 14. 



Plates 16, 17 and 33 



Plants cespitose or gregarious. Cap up to 10 cm. wide, convex, 

 smooth, not viscid, quite irregular, the margin incurved nearly to 

 maturity, remaining bent down, usually strongly lobed and crenated, 

 color grayish-brown or sordid-brown, lighter on the margin, turning 

 nearly black in age. Flesh about 8 mm. thick near stem, very thin 

 on margin, sordid white, tender, tasteless, odorless. 



Gills not crowded at stem but much closer at margin, where there 

 are very many short ones, rather narrowly adnate to the stem, not 

 sinuate and varying from not decurrent in some plants to distinctly 

 so in others, up to 6 mm. wide in middle, dingy white at maturity and 

 somewhat dingy even when quite young. The gills are very sus-
