418 NORTH AMERICAN FLORA [VoLUME 9 
Clitocybe gallinacea (Scop.) Gill. Champ. Fr. 150. 1874. (Agaricus gallinaceus Scop. Fl. 
Carn. ed. 2. 2: 433. 1772.) Described from Carniola and reported once by Peck from the 
Adirondacks, New York, occurring in grassy or mossy places. Peck states that it has a de- 
cidedly acrid taste and strong odor and that its color is dingy-white. 
Clitocybe geotropa (Bull.) Quél. Champ. Jura Vosg. 52. 1872. (Agaricus geotropus Bull, 
Herb. Fr. pl. 573/ f. 2. byponym; 1791; DC. Fl. Fr.2:172. 1805.) Reported from Massa- 
chusetts, Wisconsin, and California. 
Clitocybe Gerardiana (Peck) Sacc. Syll. Fung. 5: 181. 1887. (Agaricus (Clito cybe) 
Gerardianus Peck, Bull. Buffalo Soc. Nat. Sci. 1:46. 1873.) Described from Sandlake, New 
York, occurring in sphagnous marshes. See Omphalina Epichystum. 
Clitocybe gigantea (Sow.) Quél. Champ. Jura Vosg. 51. 1872. (Agaricus giganteus Sow. 
Engl. Fungi pi. 244. 1800.) Reported from Wisconsin by Dodge, who says it differs from 
Clitocybe maxima in having a much shorter and thicker stipe. 
Clitocybe hirneola (Fries) Quél. Champ. Jura Vosg. 49. 1872. (Agaricus hirneolus 
Fries, Syst. Myc. 1: 269. 1821.) Peck reports it once from New York. 
Clitocybe Hoffmani (Peck) Sacc. Syll. Fung. 5: 197. 1887. (Agaricus (Clitocybe) Hoff- 
mani Peck, Ann. Rep. N. Y. State Mus. 24:60. 1872.) Known only from specimens collected 
on much decayed wood in woods at Greig, New York. Not distinct from Omphalina chryso- 
phyla. . 
Clitocybe maxima (Gartn., Meyer & Scherb.) Quél. Champ. Jura Vosg. 51. 1872. 
(Agaricus maximus Gartn., Meyer & Scherb. Fl. Wett. 3?: 329. 1802.) I examined this 
species in the Hooker herbarium at Kew and elsewhere, but found no specimens from 
America and its occurrence here must be considered doubtful, although it has been reported 
from Minnesota, Massachusetts, California, and elsewhere. Peck says it is rare in the 
Adirondacks and Catskills, occurring in woods and grassy places, and that it is easily recog- 
nized by its large size. Dodge reports it from Wisconsin. 
Clitocybe megalospora Clements, Bot. Surv. Neb. 4:18. 1896. This is a form of Gym- 
nopus radicatus. See Mycologia 7: 157. 1915. 
Clitocybe morbifera Peck, Bull. Torrey Club 25: 321. 1898. Described from specimens 
collected on grassy ground and lawns in Washington, D. C., by F. J. Braendle. The taste is 
reported as very disagreeable and persisting for a long time. In Bulletin 150, Peck reports 
specimens sent by Dr. Whetstone from Minneapolis, Minnesota, and by Dr. Fischer from De- 
troit, Michigan, and in both cases sickness was produced after the fungus had been eaten in 
quantity. Dr. Peck concludes that although C. morbifera is scarcely distinguishable morpho- 
logically from C. sudorifica the ill effects of the former are much more serious and uncomfortable 
than those of the latter species. Specimens of C. dealbaia collected at Seattle were compared 
at Albany with specimens of C. morbifera collected by Dr. Whetstone in Minnesota in 1905, 
and found to agree in every particular. 
Clitocybe opaca (With.) Gill. Champ. Fr. 164. 1874. (Agaricus opacus With. Brit. Pl. 
ed. 2. 3: 307. 1792.) Reported from North Carolina by Curtis. 
Chitocybe piceina Peck, Bull. Torrey Club 31: 178. 1904. Not distinct from Melanoleuca 
albissima. 
Clitocybe pileolaria (Bull.) Murrill, Mycologia 7: 268. 1915. (Agaricus pileolarius Bull. 
Herb. Fr. pl. 400. 1788. Agaricus nebularis Batsch, Elench. Fung. Contin. 2: 25. 1789. 
Chitocybe nebularis (Batsch) Quél. Champ. Jura Vosg. 48. 1872.) Originally described from 
France, occurring among dead leaves in woods, and very well figured by Bulliard, as well as by 
Barla, Bresadola, Fries, Hussey, Bolton, and others. Peck’s figures in Report 48 are not 
suggestive of the European plant, and the spores of his specimens are 4-6 X 2-3 p, while those 
of the European plant are 8-10 X 5-7 4. The species has been reported from Canada to North 
Carolina and west to the Rocky Mountains, and there are many specimens so named at Albany, 
but apparently there remains much to be determined regarding its occurrence in this country. 
Chitocybe pintaria (Bosc) Sacc. Syll. Fung. 5: 148. 1887. (Agaricus piniarius Bosc, Ges. 
Nat. Freunde Berlin Mag. 5: 84. 1811.) Described and known only from specimens collected 
in pine woods in South Carolina. Fries did not see these specimens. 
Clitocybe porphyrella (Berk. & Curt.) Sacc. Syll. Fung.5:196. 1887. (Agaricus (Clitocybe)
