REPORT OF STATE BOTANIST, 1897 285 
globose, .00024 to .0003 in. long, nearly as broad, usually contain¬ 
ing a single large nucleus. 
Pileus 3 to 6 lines broad; stem 1.5 to 2.5 in. long, scarcely 1 line 
thick. 
Decaying trunks of yellow birch, Betnla lutea. 
It is well marked by its radicating stem and blue mycelium. Its 
flavor at first resembles that of radishes, but this soon changes in 
the mouth to a bitterish unpleasant taste. The species is referable 
to the Rigidipedes. It differs from Mycena calorhiza Bres. in its firm 
stem, its pallescent pileus and broadly elliptic or subglobose spores. 
Omphalia clavata n. sp. 
Pileus thin, convex, becoming nearly plane, glabrous, pallid or 
subcinereous, the margin decurved; lamellae narrow, distant, very 
decurrent, pallid; stem long, slender, glabrous, stuffed, commonly 
enlarged at the top, slightly villous-tomentose at the base, pallid; 
spores globose, .0002 to .00024 in. broad'. 
Pileus 2 to 4 lines broad; stem about 1 in. long, 5 lines thick. 
Dead prostrate trunks of arbor-vitae, Thuja occidental^. Ray- 
brook, Essex county. August. 
The base of the stem is clothed with a few long loose whitish fila¬ 
ments, and the thickened upper part is often fluted by the long 
decurrent lamellae. The clavate form given to the stem by this 
enlargement is suggestive of the specific name. 
Omphalia papillata n. sp. 
Pileus membranaceous, conical or campanulate, nearly even, 
papillate at the apex, pure white; lamellae few, distant, arcuate and 
strongly decurrent, white; stem filiform, glabrous, white, attached 
to- the matrix by a few radiating white filaments; spores broadly 
elliptic or subglobose, .00016 to .0002 in. long. 
Pileus 1 to 3 lines broad; stem about 1 in. long, scarcely thicker 
than a thread. 
Sticks and fallen leaves in woods. Gansevoort. July. 
The species is related to Omphalia Fibula. It should also be 
cautiously separated from Mycena immaculata.
