257 
York species have been studied very carefully by Dr. Charles 
H. Peck. 
Clitocybe adirond.\ckensis (Peck) Sacc. Syll. Fung. 
5: 180. 1887 
Agaricus adirondackensis Peck, Ann. Rep. N. Y. State Cab. 23: 
77. 1872. 
Common in woods in the Adirondack region of New York, 
where it was discovered. Very near C. inftindibidiformis, but 
distinguished by its narrow, crowded lamellae. 
Clitocybe albidula Peck, Ann. Rep. N. Y. State Mus. 46 : 103 
(23). 1893 
Clitocybe centralis Peck, Ann. Rep. N. Y. State AIus. 53 : 841. 
1900. 
Described from specimens collected under pine trees at Delmar, 
New York. It is said to be related to C. candicans. Peck re- 
duces C. centralis because it “ differs from the type only in having 
the center of the moist pileus sometimes tinged with brown.” 
The species occurs commonly in northern New York in pines or 
mixed woods and is abundantly represented at Albany. 
Clitocybe albo-umbilicata (Hoffm.) comb. nov. 
Agaricus umbilicatus Bolt. Hist. Fung, i : 36. 1795. Not A. 
umbilicatHs Schaeff. .1774. 
Agaricus candicans Pers. Syn. Fung. 456. 1801. Not A. candi- 
cans Schaeff. 1774. 
Agaricus albo-umbilicatus Hoffm. Nom. Fung. — . 1789. 
Described from Europe and reported from many parts of the 
eastern United States, occurring among fallen leaves in woods. 
Peck reports it common in New York, and I have found it plenti- 
ful in the Adirondacks. 
Clitocybe aperta (Peck) Sacc. Syll. Fung. 5:164. 1887 
Agaricus (Clitocybe) apertus Peck, Ann. Rep. N. Y. State Mus.
