Part 6, 1916] AGARICACEAE 417 
DovuBTFUL AND EXCLUDED SPECIES 
Agaricus (Clitocybe) patuloides Peck, Ann. Rep. N. Y. State Mus. 32: 25. 1880. Not 
distinct from Melanoleuca albissima. 
Chitocybe angustissima (Lasch) Gill. Champ. Fr. 168. 1874. (Agaricus angustissimus 
Lasch, Linnaea 4: 528. 1829.) Reported by Peck as rare in New York. 
Clitocybe caespitosa Peck, Ann. Rep. N. Y. State Mus. 41:61. 1888. Described from the 
Catskill Mountains, New York, and found afterwards in the Adirondacks. It is a rare species, 
occurring in clusters in woods, and is remarkable for its irregular and deformed appearance. 
Specimens at Albany collected in Michigan by Beal resemble a young, subclustered stage of 
C. adirondackensis, and it seems probable that further studies may connect the two species. 
Chtocybe candida Bres. Fungi Trid. 1:16. 1882. Reported from New York but doubt- 
less confused with C. robusta Peck. 
Chitocybe cerussata (Fries) Quél. Champ. Jura Vosg. 49. 1872. (Agaricus cerussatus 
Fries, Syst. Myc. 1: 92. 1821.) Reported by Peck as occurring rarely in the Adirondacks, 
as well as in certain other localities in America. 
Clitocybe chrysocephala Sacc. Syll. Fung. 5: 190. 1887. (Agaricus (Clitocybe) aurato- 
cephalus Ellis, Bull. Torrey Club 6: 75. 1876.) Described from Newfield, New Jersey, 
occurring there in swampy ground in July. See Camarophyllus auratocephalus. 
Clitocybe columbana (Mont.) Sacc. Syll. Fung. 5: 142. 1887. (Agaricus (Chitocybe) 
columbanus Mont. Syll. Crypt. 102. 1856.) Described from specimens collected on naked 
ground at Columbus, Ohio. The types at Paris are large, closely clustered, and have the 
appearance of Monadelphus illudens, but the spores are ellipsoid, 7 X 44. The color of the 
plant when fresh is not stated in the description. 
Clitocybe difformis (Schum.) Gill. Champ. Fr. 172. 1874. (Agaricus difformis Schum. 
Enum. Pl. Saell. 1: 335. 1803.) Reported once from New York by Peck. It has usually 
been regarded as a form of C. cerussata. 
Chtocybe ditopoda (Fries) Gill. Champ. Fr. 166. 1874. (Agaricus diiopus Fries, Syst. 
Myc. 1: 171. 1821.) Reported by Peck as rare in New York. 
Clitocybe ectypa (Fries) Gill, Champ. Fr. 172. 1874. (Agaricus ectypus Fries, Syst. 
Myc. 1: 108. 1821.) Reported from Alabama by Atkinson. 
Chitocybe ectypoides (Peck) Sacc. Syll. Fung. 5: 169. 1887. (Agaricus (Clitocybe) ecty- 
poides Peck, Ann. Rep. N. Y. State Mus. 24:61. 1872.) Described from Sandlake, New York, 
and occurring rather frequently on decaying wood in woods from Maine to Alabama and west 
to Wisconsin. Apparently not distinct from Omphalina chrysophylla. 
Clitocybe elixa (Sow.) P. Karst. Bidr. Finl. Nat. Folk 32: 69. 1879. (Agaricus elixus 
Sow. Engl. Fungi pi. 172. 1798.) Reported from Massachusetts and Rhode Island. 
Chitocybe erubescens (Mont.) Sacc. Syll. Fung. 5: 150. 1887. (Agaricus (Clitocybe) 
erubescens Mont. Syll. Crypt. 103. 1856. Not A. erubescens Fries, 1821.) Described from 
specimens collected on fallen logs at Columbus, Ohio, by Sullivant. The types at Paris, which 
are poorly preserved, suggest either a true Clitocybe or a species of Camarophyllus, near C. ful- 
vosus. The stipe is thick; the lamellae narrow to broad and distant; and the pileus smooth, 
viscid, and 2.5 cm. broad in its present dried state. The spores are oblong-ellipsoid, somewhat 
fusiform, smooth, hyaline, 4-5 X 2-3 nu. 
Clitocybe flaccida (Sow.) Quél. Champ. Jura Vosg. 329. 1873. (Agaricus flaccidus Sow. 
Engl. Fungi pl. 185. 1799. Not A. flaccidus Bull. 1788.) Described from England and 
reported as occurring in pine woods in Massachusetts and Maryland. A study of Sowerby’s 
plate and of specimens at Kew, in connection with specimens collected at Paris, leads me to 
believe that this is none other than C. inversa; in which case its occurrence in this country is 
correctly reported. 
Chitocybe fragrans (Sow.) Quél. Champ. Jura Vosg. 55. 1872. (Agaricus fragrans 
Sow. Engl. Fungi pl. 10. 1795.) Reported by Peck as rare in New York. Also reported from 
North Carolina and California.
