REPORT OF THE DIRECTOR I918 5I 



DISTICHIUM CAPILLACEUM, B. & S. 



Wet rocks and precipices. Adirondack mountains, Cascadeville. 

 June. The distichous arrangement of the leaves, characteristic of 

 the genus, is not very conspicuous in this moss, which at first sight 

 somewhat resembles Dicranella heteromalla. 



CALICUM EUSPORUM, Nyl. 



Bark of dead balsam, Abies balsamea. Chapel pond, Adiron- 

 dack mountains. June. This rare lichen has but recently been 

 detected in this country. Mr. Willey informs me that he first 

 found it about a year ago in the White mountain region. 



COLLYBIA FULIGINELLA, N. sp. 



Pileus convex or nearly plane, sometimes irregular or undulate 

 on the margin, glabrous, even, fuliginous-brown, flesh white; 

 lamellae, rather narrow, close, rounded behind, adnexed or nearly 

 free, white; stem equal or slightly tapering upward, subfibrillose, 

 stuffed or hollow, colored like the pileus or a little paler, white 

 tomentose at the base; spores subelliptical, .0003 to .00035 inch 

 long, .0002 to .00025 broad, usually containing a single large 

 nucleus. 



Pileus 1.5 to 2.5 inches broad, stem 1.5 to 2 inches long, 2 to 3 

 lines thick. 



Under or near arbor-vitae, Thuja occidentalis. Elizabethtown, 

 Essex county. September. 



In size and shape this species resembles CoUyhia dryophila, but 

 its color, which closely resembles that of Lacterius Ugnyotus, is 

 far different. 



CLITOPILUS SUBVILIS, N. sp. 



Pileus thin, centrally depressed or umbilicate, with the margin 

 decurved, hygrophanous, dark-brown and striatulate when moist, 

 grayish-brown and silky-shining when dry; lamellae subdistant, 

 adnate or slightly decurrent, whitish when young, then flesh-colored; 

 stem slender, brittle, rather long, stuffed or hollow, glabrous, colored 

 like the pileus or a little paler; spores irregular, angular, .0003 to 

 .0004 inches long; odor weak or none, taste farinaceous. 



Pileus 8 to 1 5 lines broad, stem 1.5 to 3 inches long, i to 2 lines 

 thick. 



Damp soil in thin woods. Karner, Albany county. October. 



The species seems to be closely related to Clitopilus vilis, from
