AGARICALES 127 



C. pruniilus is more compact, with a dry, pruinate pileus and 

 is slightly larger than the preceding species. 



The remaining genera, Entolovia, Nolanea and Leptonia, have 

 adnate or sinuate lamellae ; like the species of Eccilia they have 

 angular spores. Entoloma, with twelve species, has a fleshy stem 

 while that in the other two genera is cartilaginous. Nolanea, 

 with seven species, is characterized by its bell-shaped, smooth or 

 papillose pileus and straight margin, while Lcptonia, with six 

 American species, has a low arched scaly pileus with the margin 

 at first incurved. None of these genera possess species of eco- 

 nomic interest and in general it may be said that the pink-spored 

 agarics are the least important of any, though those with rusty 

 brown spores follow closely behind. 



E. With white spores. 



The white-spored members of the Evelatae are very numerous 

 and vary greatly in size and habit. Two genera, Ouiphalia * and 

 Clitocybt',-\ have decurrent lamellae and can thus be easily recog- 

 nized. The former has a cartilaginous stem, while in Clitocybe 

 the stem is fleshy and continuous with the substance of the pileus. 

 Some of the species of Clitocybe are edible, the most common 

 of which are the following : 



C. infundibuliformis, with a funnel-shaped pileus two or three 

 inches across. 



C. nebularis and C. media, thick and fleshy, the former grayish 

 with close lamellae and the latter brown with lamellae distant. 



C. clavipes is top-shaped with a brownish pileus often slightly 

 umbonate. 



C. laccata is pinkish, with more or less waxy lamellae. Some 

 are inclined to regard this species and its congeners as forming a 

 distinct genus. 



In the same genus is the gorgeous C. illudens, a large golden- 

 yellow species, often growing in immense clusters at the base of 



* Omphalia contains twenty-five or more American species. Peck 

 (Reg. Rep. 45 : 32-42) describes twenty-one of these which occur in 

 New York. 



f Clitocybe contains about forty American species. Morgan (Jour Cin- 

 cinnati Soc Nat. Hist. 5 : 66-70) describes thirteen species ; no complete 

 synopsis of the American species has yet appeared.
