110 NORTH AMERICAN FLORA [Vo.umE 10 
DouBTFUL AND EXCLUDED SPECIES 
Clitopilus cancrinus (Fries) Quél. Champ. Jura Vosg. 227. 1872. (Agaricus cancrinus 
Fries, Epicr. Myc. 150. 1838.) Reported by Peck from New York and by Ellis from New 
Jersey, but no satisfactory American specimens have been seen. 
Clitopilus carneo-albus (With.) Gill. Champ. Fr. 409. 1876. (Agaricus carneo-albus 
With. Brit. Pl. ed. 4. 4: 167. 1801.) Reported by Ravenel, Peck, Miss White, and others, 
but none of the specimens seen appear to be correctly determined. 
Clitopilus connissans Peck, Ann. Rep. N. Y. State Mus. 41: 64. 1888. This species 
was transferred to the genus Psilocybe by Peck in Bull. N. Y. State Mus. 122: 131. 1908. 
Chitopilus Davisii Peck, Bull. Torrey Club 36: 153. 1909. Specimens collected by 
Murrill and House in North Carolina show this species to belong to the genus Enioloma. 
Clitopilus popinalis (Fries) P. Karst. Bidr. Finl. Nat. Folk 32: 270. 1879. (Agaricus 
popinalis Fries, Syst. Myc. 1: 194. 1821.) Reported from New York by Peck and said 
to occur also in other parts of North America. In describing Clitopilus abortivus, Berkeley 
said it was near C. popinalis, which is also frequently abortive, but distinguished by its downy 
pileus and the gills not being gray. Fries’ figures of C. popinalis represent a large, thick, and 
umbonate plant which is very dark in color both without and within. It is probable that 
Pleuropus noveboracensis and P. abortivus will account for most of the specimens in North 
America determined as Clitopilus popinalis. : 
Clitopilus stilbocephalus (Berk. & Br.) Sacc. Syll. Fung. 5: 705. 1887. (Agaricus stilbo- 
cephalus Berk. & Br. Ann. Mag. Nat. Hist. V. 3: 205. 1879.) Reported from New York 
by Peck. See Pleuropus Underwooditi. 
Chitopilus undatus (Fries) P. Karst. Bidr. Finl. Nat. Folk 32: 271. 1879. (Agaricus 
undatus Fries, Epicr. Myc. 149. 1838.) Reported from Greenland and Minnesota. 
57. LEPISTA (Fries) W. G. Sm. Clavis Agar. 26. 1870.

teristic. 1

Tricholoma sordidum Quél. Champ. Jura Vosg. 47, 1872. 
Clitocybe tarda Peck, Bull. Torrey Club 24: 140. 1897. 
Clitopilus tardus Peck, Ann. Rep. N. Y. State Mus, 54: 167. 1901, 
Rhodopaxillus sordidus Maire, Ann. Myc. 11: 338. 1913. 
Melanoleuca sordida Murrill, Mycologia 6: 3. 1914. 
Lepisia domestica Murrill, Mycologia 7: 106. 1915. 
Pileus thin, convex to plane or slightly depressed, subumbonate at times, often irregular, 
gregarious or cespitose, 3-7 cm. broad; surface smooth, glabrous, pale-violet to avellaneous 
with ochraceous hues, usually fuliginous on the disk, margin naked, involute when young; 
context violaceous to whitish, mild, edible; lamellae sinuate to slightly decurrent, narrow, 
crowded, concolorous when young, fading with age, the edges often eroded; spores ellipsoid,
