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. 

 ftussuLA heterophylla, Fr. 



Woods. East Berne. August. 

 Marasmius salignus, n. sp. 



Pileus submembranous, convex or plane, without striae, dry? 

 glabrous or subpruinose, whitish ; lamellae 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 M. 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. 



POLYPORUS (MERI8MA) IMMITIS, 11. Sp. 



Pilei caespitose-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. ccesareus, but the char- 

 acter of the pores is quite different in the two species.
