B. Stipe lateral, 76. 



C. Stipe none ; pileus sessile. 



c. Pileus uniform, 77, 78. 



d. Pileus gelatinous, 79, 80. 



A. Pileus entire, the stipe excentric. 



a. LamellcB sinuate or obtusely adnate. 



69. A. ULMARius, Bull. — Pileus fleshy, compact, convexo-plaue, glab- 

 rous, somewhat spotted, moist. Stipe rather excentric, thickened 

 downwards, somewhat tomentose. Lamellae attached, rather close, 

 broad, whitish. Spores nearly globose, .005 mm. long. 



Upon trunks of trees, especially elm, frequent; in autumn. Pileus 

 3-7 in. broad, or sometimes larger, whitish or pale brownish, sometimes 

 marbled with livid spots; stipe ascending, 2-3 in. long, about 1 in. 

 thick, solid. Solitar}^ or csespitose. 



70. A. SDBPALMATUS, Fr. — Cffispitose, reddish. Pileus fleshy, soft, 

 convexo-plane, obtuse, wrinkled; the cuticle gelatinous. Stipe ex- 

 centric, incurved, equal, fibrillose. Lamellre adnate, close, joined 

 behind. Spores minutely echinulate, nearl}'^ globose, .0056-.0070 mm. 

 long. 



On timber, old trunks, etc. This curious species was sent me from 

 Brookville, Ind„ by Mr. O. M. Meyucke; this appears to be the first 

 locality in which it has been met with in this countr3% The specimens 

 1 have seen are l|-2 in. wide, with a stipe f-1 in. long. The British 

 plant measures 3-4 in. broad, with a stipe of 1-2 in. 



71. A. cuASPEDiDS, Fr. — Cajspitose. Pileus fleshy, more or less ex- 

 centric, crenate and lobed, even, glabrous. Stipe solid, firm, elastic, 

 glabrous, pallid. LamelliB adnate, close, narrow, white. Spores 

 nearly globose, .0056 mm. in diameter. 



On trunks in woods. Pileus 3-5 in. broad, stipe 2-3 in. long. The 

 whole Y)lant is quite hard and tough; the pileus in my specimens, 

 grayish or brownish, the margin much folded and lobed; the stipe 

 rather thicker below. This seems to be the first record of it in North 

 America. 



72. A. LiGNATiLis, Fr. — Pileus fleshy, toiigli, convex then plane of 

 umbilicate, irregular, at first flocculose-pruinose, afterward glabrous. 

 Stipe stuffed then hollow, rather slender, irregular, somewhat villous. 

 LamelljB aduate, close, narrow, white. Spores .003.004 mm. long.
