Part 6, 1916] AGARICACEAE 419 
porphyrellus Berk. & Curt. Ann. Mag. Nat. Hist. III.4:284. 1859.) Described from specimens 
collected in leaf-mold in Connecticut by Wright. The types at Kew are badly molded and 
unreliable for comparison. The pale-purple color of the entire hymenophore would seem 
to suggest Prunulus purus or one of the species of Laccaria. 
Chtocybe pruinosa (Lasch) Quél. Champ. Jura Vosg. 216. 1872. (Agaricus pruinosus 
Lasch; Fries, Epicr. Myc. 75. 1838.) Reported from Ohio by Lea. 
Clitocybe pruinosa Lovejoy, Bot. Gaz. 50: 384. 1910. Not Clhitocybe pruinosa (Lasch) 
Quél. 1872. Described from specimens collected in open pine woods at Foxpark, Wyoming, 
August 14,1909. The pileus is described as 3.5 cm. wide, smooth, and rich-reddish-brown over 
salmon; the lamellae as salmon-yellow, crowded, and very decurrent; and the spores as globose, 
spiny, 7-10.5 w. This would seem to indicate a species of Laccaria if the lameflae were not so 
decurrent. Its relationship may be with C. sinopica. 
Clitocybe radiozonaria (Johnson) Sacc. Syll. Fung. 9: 20. 1891. (Agaricus (Chitocybe) 
radiozonarius Johnson, Bull. Minn. Acad. Sci. 1: 214. 1877.) Described from Minnesota, 
occurring on decaying fallen branches and stumps in June. The specimens are lost, but the 
description resembles that of Crinipellis zonata. : 
Chtocybe rancidula (Banning & Peck) Murrill, Mycologia 7: 270. 1915. (Tricholoma 
rancidulum Banning & Peck; Peck, Ann. Rep. N. Y. State Mus. 44: 179 (67). 1891.) Known 
only from specimens collected in vegetable mold in Druid Hill Park, Baltimore, Maryland, by 
Miss Banning. The lamellae are slightly decurrent and very narrow and crowded. The 
plant is larger than Lepista personata, the stipe is not bulbous, and the margin of the pileus 
is finely striate for about 2cm. Its odor is very rancid, whence the name. 
Clitocybe rivulosa (Pers.) Quél. Champ. Jura Vosg. 214. 1872. (Agaricus rivulosus Pers. 
Syn. Fung. 369. 1801.) Described from Europe and twice reported by Peck from the 
Adirondacks. It was also reported from the Antilles by Fries in 1851. 
Clitocybe setiseda (Schw.) Sacc. Syll. Fung. 5: 176. 1887. (Agaricus (Omphalia) setisedus 
Schw. Schr. Nat. Ges. Leipzig 1: 88. 1822.) Described from North Carolina, occurring 
among fallen leaves. I have seen no specimens. 
Clitocybe socialis (Fries) Sacc. Syll. Fung. 5: 149. 1887. (Agaricus socialis Fries, Hymen. 
Eur. 83. 1874.) Reported by Moffatt as occurring among dead leaves on a wooded hillside 
in the vicinity of Chicago, Illinois. He says that it is remarkable for its very acute umbo, and 
that the spores are globose, echinulate, 9-10». Ihave not seen his specimens. 
Clitocybe splendens (Pers.) Gill. Champ. Fr. 139. 1874. (Agaricus splendens Pers. Syn. 
Fung. 452. 1801.) Described from Europe and reported by Peck as rare among fallen leaves 
in woods in the Adirondacks. It is very probable that American specimens bearing this name 
may all be referred to C. sinopica, C. subsquamata, or C. tnversa, 
Clitocybe subinvoluta (Batsch) Sacc. Syll. Fung. 5: 170. 1887. (Agaricus subinvolutus 
Batsch, Elench. Fung. Contin.-2: 57. 1789.) Reported from Massachusetts by Frost and 
from New York by Peck. 
Clitocybe subsimilis Peck, Ann. Rep. N. Y. State Mus. 41: 61. 1888. Described from 
specimens collected tmder pine trees in the Catskill Mountains, New York. After examining 
the excellent type specimens at Albany, I have referred the species to Melanoleuca albissima 
(Peck) Murrill. 
Clitocybe subsocialis Peck, Bull. Torrey Club 23: 411. 1896. Described from specimens 
collected by Yeomans on grassy ground at Camas, Washington, in December. Peck remarks 
that it is closely related to C. socialis, but differs in its strong odor, squamulose pileus, and white 
lamellae, The types at Albany very much resemble C. sinopica, but Peck says they differ 
from this species in their squamulose surface, although resembling it in color. 
Chitocybe sudorifica Peck, Bull. N. Y. State Mus. 157: 67. 1912. (Clitocybe dealbata 
sudorifica Peck, Bull. N. VY. State Mus. 150: 43. 1911.) First described as a variety of 
C. dealbata from specimens collected in grassy ground at Saratoga, New York, by F. G. How- 
land. It has been collected in two or three other localities in Albany and Ontario Counties. 
Mr. Howland, Dr. Peck, and Dr. Ford all agreed that this mushroom was decidedly sudorific 
and unwholesome, differing decidedly in this respect from the reputation enjoyed by C. dealbata. 
I have examined the types, however, anid can see no morphologic difference between the two
