Clitopilus tardus Pk. (late). 



East Hartford, Jan., greenhouse, Hanmer. 

 Clitopilus unitinctus Pk. (one-colored). 



East Hartford, Hanmer. 



ECCILIA Fr. 



iyKotXor,, hollowed out. 



This small genus has characters similar to those of Oni- 

 phalia of the white-spored group. The pileus is depressed in 

 the center, and when young the margin is inrolled. The stem 

 is brittle as in Entoloma, but the gills differ by extending down 

 the stem (decurrent). 



Eccilia carneo-grisea B. and Br. (grayish flesh-colored). 

 East Hartford, Hanmer. 



AGARICUS Linn. 



'AyapiKov, a name for a fungus. 



This genus is one of the most interesting in the Agari- 

 cacere because of the economic importance of many of the 

 species. It contains some of the best known species, and 

 their marked characters prevent their being confused with 

 poisonous or harmful mushrooms. The entire plant is more 

 or less fleshy, and the stem has a distinct ring ; in some spe- 

 cies it disappears as the plant matures, but in the young plant 

 it is quite distinct, and is formed by the rupturing of the veil, 

 which at first encloses the gills. The gills arc free from the 

 stem, which easily distinguishes the genus from Stropharia, 

 and the abundance of brown spores which are formed on the 

 under surface of the gills in mature plants, together with the 

 presence of a ring upon the stem, prevent its confusion with 

 other genera. The species strongly resemble some of the 

 Lepiotas of the white-spored group. As far as known, no spe- 

 cies are poisonous. A. campestris occurs in considerable 

 quantities in the vicinity of Mansfield, and its long season of 

 growth makes it a valuable species. It is one of the most fa- 

 miliar species, and nearly every one, even the most inexpe- 

 rienced collector, is familiar with " those toadstools which are 

 pink or brown on the under side." This common field or pas-
