On wood of beech and maple. Pileus 1-3 in, broad, stipe an inch or 

 less in length. Cominonl}' whitish, with a strong mealy odor. 



b. Lamellce. decurrent. 



73. A. coRTiCATDS, Fr. — Pileus compact, entire, densely villous, at 

 length floccose-scaly. Stipe firm, rooting, somewhat excentric, 

 fibrillose; annulus membranaceous, lacerate. Lamellaa decurrent, 

 rather distant, divided, white, anastomosing behind. Spores large, 

 elliptic-oblong, .OllX-005 mm. 



On trunks in woods. Pileus in m}^ specimens about 4 in. in 

 diameter, the stipe 2-3 in. long. These specimsns which were very few 

 in number, may have been the variet}^ tephrotrichus ; the annulus was 

 obsolete with the veil appendiculate around the margin of the pileus. 

 The whole plant was clear white. 



74. A. SAPiDus, Kalch, — Csespitose. Pileus flesh}-, somewhat ex- 

 centric, deformed, glabrous; the center depressed. Stipes solid, 

 arising out of a common fleshy tubercle, glabrous, white. Lamellae 

 decurrent, rather distant, whitish. Spores with a lilac tinge, oblong, 

 or a little curved and pointed, .0083X-^037 mm. 



Very common on all sorts of fallen trunks and branches, from eai-ly 

 spring till late in autumn, and even in the mild weather of winter. 

 Pileus commonly 3-6 in. in diameter, the stipe 1-2 in. long or the 

 pileus nearly sessile. The plant is various in form and color, being 

 commonly white or clouded with brown; the flesh is always white. 

 Clear white paper will disclose the lilac tint of the spores. 



75. A. SALiGNUs, Abb. d. Schw.— Pileus fleshy, compact, spongy, 

 somewhat dimidiate, horizontal, at first pulvinate, even, afterward the 

 disk depressed, somewhat strigose. Stipe short, toraentose. Lamellaj 

 decurrent, some of them branched, eroded, distinct at the base, nearly 

 the same color as the pileus. Spores .009X-0038 ram. 



" Upon trunks of willows late in autumn, solitary." — Fries. Pileus 

 convex, 4-6 in. broad, stipe excentric or lateral, sometimes obsolete ; 

 commonly fuliginous-cinereous, though sometimes ocliraceous. Lea's 

 Catalogue is authority for this plant. " On a prostrate buckeye, Cin- 

 cinnati, December." It is strange that sapidus, so common as it is, is 

 not in Lea's Catalogue. Unless salignus shall yet be verified, we must 

 conclude that Mr. Lea mistook sapidus for salignus. 



B. Pileus definitely lateral, not marginate behind. 



76. A. SEROTINUS, Schrad.— Pileus fleshy, compact, viscid. Stipe ex-
