the latter reticulate with obtuse folds, incompletely porous, at 

 length gyrose and obsoletely dentate. l''ungi epixylous. 



a. Pileiis sessile, dimidiate. 



1. M. RUBEM.us, Peck. Pilei sessile, confluent and iiuliri- 

 cated, repand, thin, convex, somewhat tenacious, subtomentose, 

 glabrate, red becoming pale. Hymenium. whitish or reddish ; the 

 folds much branched," porose-anastomosing. Spores white, ellip- 

 tic, .004-005 mm. long. 



In woods on old trunks and branches; not uncommon. Pileus 

 1--3 inches in breadth, or confluently several inches. This is a 

 very beautiful species, never resupinate or effuso-reflexed as the 

 following ones, but always sessile and more or less confluent and 

 imbricated; the color varies from flesh-color to deep red, fading 

 out with age ; the hymenium is commonly an elegant cream-color, 

 but sometimes it is ])ure wliiie, and occasionally it is tinged with 

 red. This is most likely the M. incaniatiis, Schw., of Lea's Cata- 

 logue, but specimens compared with those of this species in 

 Schweinitz's herbarium were declared to be different ; furthermore, 

 in the N. A. Fungi, Schweinitz insists that his species is incorrectly 

 referred to Merulius, and is a Cantharellus. 



I). Pileus cffuso-rcficxcd, witJi a dctcnninatc border. 



2. "M. TKEMELLosus, Schrad. Resupinate; then free or re- 

 flexed, fleshy-tremellose, tomentose, white, the margin dentate ra- 

 diate. I'olds porose, various in form, reddish. S[)ores white, a 

 little curved, .004-. 005 mm. long. 



In woods on old trunks and branches; common. Substance 

 cartilaginous-gelatinous, the younger fungus all resupinate, orbicu- 

 lar, pallid, with a radiate and free border ; at length becoming 

 reflexed sometimes to the extent of an iiuh, and much confluent 

 and even imbricated; in dryi'ng, the color changes to alutaceous, 

 and that of the hymenium to brownish. 



3. iM. CURIUM, Fr. Resupinate-effused, soft, subpapyraceous ; 

 the border at length free, reflexed, villous underneath, white. Hy- 

 menium reticulate porose, flesh-color or pale alutaceous. 



In woods on bark of Sugar Maple; rare. My specimens are 

 an inch or more in breadth and y-^ inches long, w ith a \ery narrow 

 reflexed border ; at first they were nearly while, but in drying have 

 taken on a fleshy tint. In the Handbook of IJritish i'ungi, the 

 spores are said to be vivid orange, oval, .006 mm. hnig.
