THE BLACK-SPORBD AGARICS 345 



Panceolus papilionaceus. Fr. 

 The Butterfly Panaeolus. 



Papilionaceus is from papilio, a butterfly. 



The pileus is about an inch broad, somewhat fleshy, at first hemispherical, 

 sometimes subumbonate, the cuticle breaking up into scales when dry, as will be 

 seen in the photograph, pale-gray with a tinge of reddish-yellow especially on the 

 disk, sometimes smooth. 



The gills are broadly attached to the stem, quite wide, at length plane, blackish 

 or with varying tints of black. 



The stem is three to four inches long, slender, firm, equal, hollow, powdered 

 above, whitish, sometimes tinged with red or yellow, slightly striate at the top, 

 as will be -seen in the photograph with a glass, generally stained with the 

 spores. 



The specimens in Figure 279 were found in a garden that had been strongly 

 manured. It is usually found on dung and on grassy lawns during May and 

 June. Captain Mcllvaine in his book speaks of this mushroom producing hilarity 

 or a mild form of intoxication. I should advise against its use. 



Ancllaria. Karst. 



Anellaria is from (melius, a little ring. This genus is so called because of 

 the presence of a ring on the stem. 



The pileus is somewhat fleshy, smooth, and even. The gills are adnexed, 

 dark slate-colored, variegated with black spores. The stem is central, smooth, firm, 

 shining, ring persistent or forming a zone around the stem. 



Anellaria separata. Karst. 



Separata means separate or distinct. 



The pileus is somewhat fleshy, bell-shaped, obtuse, even, viscid, at first 

 ochraceous, then dingy-white, shining, smooth, wrinkled when old. 



The gills are firmly attached to the stem, broad, ventricose, thin, crowded, 

 clouded, cinerous, margin nearly white, slightly deliquescent. 



The stem is long, straight, shining, white, thickened downward, ring distant, 

 top somewhat striate, bulbous at the base. The spores are broadly eliptic-fusiform, 

 black, opaque, 10x7^. 



It : s found on dung from May to October. It is not poisonous.
