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 I have 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. inversa. 
Clitocybe subconcava Peck, Bull. N. Y. State Mus. 54: 948. 
1902 
Described from Bolton, New York, growing in pine woods. 
There are seven specimens on the type sheet at Albany, but the 
species has not been reported since. It should be carefully com- 
pared with forms of C. sinopica. 
Clitocybe subconnexa sp. nov. 
Pileus convex to expanded, rather thin, very tender and fragile, 
somewhat cespitose, reaching 9 cm. broad ; surface smooth, dry, 
glabrous, milk-white ; margin very thin, concolorous, entire, 
strongly incurved on drying; context thin, white, fragile, with 
pleasant odor and taste ; lamellae short-decurrent or adnate, 
narrow, white, exceedingly crowded, several times inserted ; 
spores ellipsoid, smooth, hyaline, 5 X 3-5 stipe fleshy, subequal, 
smooth, glabrous, white, hollow, 5-7 cm. long, reaching 1.5 cm. 
thick. 
Type collected in rich soil under trees in the New York 
Botanical Garden, September 26, 1911, W. A. Murrill. Also 
collected in the grass near the herbaceous nursery of the New 
York Botanical Garden, September 25, 1907, R. C. Benedict. 
This species somewhat resembles C. multiceps but it is thinner 
and more fragile and the lamellae are much more crowded.
