STROPHARIA SEMIGLOBATA. 

 (Fig. 34) 



(POISONOUS) 



In Stropharia semiglobata the cap is rounded, then hemispherical, thick at 

 center, becoming thin toward the even margin, light yellow, viscid when moist ; 

 the gills are broad, adnate, unequal, when young light brown, later purplish 

 brown or blackish ; the stem is slender, hollow, even or slightly bulbous,

smooth, yellowish, but paler at apex, where striate markings from the gills may 

 be present, viscid ; the ring is viscous, incomplete, and formed by the remains 

 of the glutinous veil which soon disappears. 



Figure 35. — Hypholoma appendiculatum. (Edible.) (From G. F. Atkinson) 



The cap is 1 to 1% inches broad ; the stem is 2 to 3 inches long and 2 to 3 

 lines thick. 



This species is remarkable for the uniformly hemispherical cap. It occurs 

 commonly on dung or in well-manured ground. It is not to be recognized as 

 an edible species.
