REPORT OF THE STATE BOTANIST. 135 
This, like the preceding one, has a short white space at the top of 
the stem, free from the viscidity that exists elsewhere. It re- 
sembles in many respects Hygrophorus speciosus, which has the 
pileus red, fading to yellow with advancing age. Perhaps the 
* three may yet prove to be forms of one very variable species, for 
the most conspicuous differences between them consist in the 
colors of the pileus. The constancy with which the three styles 
of coloration has thus far been maintained indicates a specific 
difference, but color alone is not generally regarded as having any 
specific value. 
RussULA HETEROPHYLLA, 7. 
Woods. East Berne. August. 
MARAS MIUS SALIGNUS, 7%. sp. 
Pileus submembranous, convex or plane, without striz, dry, 
glabrous or subpruinose, whitish ; lamelle rather narrow, adnate, 
subdistant, whitish, sometimes united behind in pairs, occa- 
sionally branched; stem short, slender, stuffed, reddish-brown, 
slightly mealy or pruinose, inserted ; spores ovate or subelliptical, 
pointed at one end, -00025'—-00032’ long, 00016’ broad. 
Plant 6’—10" high, pileus 2"—5’ broad, stem scarcely half a 
line thick. 
Bark of living willow trees. Bethlehem. September. 
This species is closely related to If. ramealis, but in that species 
the pileus, according to the description, is rufescent either wholly 
or on the disk, and the stem is white ; in our species the pileus is 
white or whitish and the stem is reddish-brown. Only in young 
specimens is the stem white and then only at the apex. Some- 
times there is a slight depression or umbilicus in the center of the 
pileus. 
Potyporus (MERISMA) IMMITIS, 2. sp. 
Pilei cxespitose-imbricated, broad, slightly convex or flattened, 
more or less rough or uneven, radiate-rugose, tuberculose or fibrous- 
hispid, zoneless, white, becoming tinged with yellow or alutaceous 
in drying, flesh white, slightly fibrous, soft and moist when fresh, 
cheesy when dry, with a subacid odor; pores minute angular or 
even subflexuous, about equal in length to the thickness of the 
pileus, the dissepiments thin, white, often at length dentate or 
lacerate on the edge; spores minute, white, elliptical, -00012’— 
-00016’ long, -00007’—-00008’ broad. 
Pilei 2’— 4! broad, the flesh commonly 3’— 4" thick. 
Decaying ash trunks, East Berne. August. 
The species is apparently related to P. cwsareus, but the char- 
acter of the pores is quite different in the two species,
