On the ground in woods, amongst moss and decaying 

 leaves. Autumn. Qualities unknown. 



From 1 to 3 inches high ; about J of an inch in 

 broadest part. The club-shaped head is generally obtuse 

 at the summit, and terminates abruptly and unevenly 

 at the base, occupying about one-third to one-half the 

 entire length of the plant, not unfrequently compressed, 

 glabrous, and, when wet, slippery; the stem is cylindrical, 

 squamulose, rather paler than the head ; the flesh is also 

 green ; the asci are narrowly clavate ; the sporidia 

 elliptic-oblong ; paraphyses abundant ; gelatina hymenia 

 greenish. The sporidia in my Herefordshire specimens 

 did not exceed the size given above, but Dr. Cooke 

 (" Mycogr.") gives 30 X
