Report of the State Botaxist. 133 



The elliptical spores and viscid pilous are distinguishing char- 

 acters in this species. The pileus is often stained by the spores 

 and it then has a sordid or squalid appearance. When not so 

 stained it is very white if dry, watery-white if moist. The 

 margin is very thin. The lamellas are dingy, when young, and 

 they become darker with age. The stem is wanting or merelv 

 rudimentary. The pileus is attached by white filaments. 

 Agaricus (Crepidotus) tiliophilus, n. sp. 



Pileus rather thin, convex, minutely pulverulent or subglabrous, 

 hygrophanous, watery-brown and striatulale on the margin 

 when moist, dingy buff-color when dry ; lamellge rather broad, 

 subdistant, rounded behind, adnesed, colored like the pileus, be- 

 coming ferruginous-cinnamon; stem very short, often curved, 

 solid, eccentric, whitish, pruinose, with a white pubescence at the 

 base ; spores ovate or subelliptical, brownish-ferruginous, '0002' — 

 •00025' long, -00016' — 00018' broad. 



Pileus 6" — 12" broad, stem 2" — 4" long, 1" thick. 



Dead trunks and branches of basswood, Tilia Americana. East 

 Berne. Aus^ust. 



Sometimes the plants are so closely crowded that they appear 

 csespitose . 

 Agaricus (Hypholoma) nitidipes, n. sp. 



Pileus fleshy, firm, convex, glabrous or obscurely fibrillose, 

 whitish or yellowish ; lamellas close, adnexed, whHish or subcin- 

 ereous, becoming rosy-brown, generally white on the edge ; stem 

 equal or slightly thickened at the base, solid, silky, shining, 

 whitish; spores ovate, rosy-brown, -0002' — 00025' long, '00016' — 

 •00018' broad. 



Plant 2' — 4 high, pileus 2' — 3' broad, stem 3' — 4 ' thick. 



Damp, shaded ground. Albany. September. 



Externally this species resembles A. prcecox, from which its solid 

 stem and smaller spores at once distinguish it. 

 Agaricus (Panjeolus) epimtces, «. sp. 



Pileus fleshy, at first subglobose, then convex, white, silky- 

 fibrillose, flesh soft, white or whitish ; lamellae rather broad, some- 

 what close, rounded behind, adnexed, dingy-white, becoming 

 brown or blackish, with a white edge; stem short, stout, tapering 

 upwards, strongly striate and minutely mealy or pruinose, solid 

 in the young plant, hollow in the mature plant, but with the 

 cavity small, hairy or substrigose at the base ; spores elliptical, 

 black, .0003' — 00035' long, .0002' — 00025' broad. 



Plant 1' — 1-5' high, pileus 8" — 12" broad, stem 3" — 4* thick.
