rimose-parted or if entire soluble. Fungi resupinate, lignatile, of- 

 ten sterile. 



I. LoMATiA. Resupinate, but the border free, determinate, 

 marginate, commonly from cupular expanded. 



1. C. AMORPHUM, Pers. Waxy-pliant, subcoriaceous, cup- 

 shaped then explanate, confluent, marginate, externally white- 

 tomentose. Hymenium even, contiguous, becoming pallid ; spores 

 obliquely elliptic, apiculate, .025 x .017 mm. 



On the bark of living trees of Ostrya Virginica ; common. At 

 first looking like a small Peziza from an eighth to a quarter of an 

 inch in diameter, but at length irregularly confluent, sometimes to 

 the extent of an inch or two, always preserving however the free 

 border which is rolled inward when dry. It is C. Oakesii, B. & C. 



II. HiMANTiA. Resupinate, eff"used, immarginate ; the border 

 and underside byssine-fibrillose or strigose-hairy. 



Often sterile, then fibrillose ; in its perfect state, the hymenium 

 soft-waxy. 



2. C. LACTEUM, Fr. Eff'used, membranaceous, milk-white ; 

 the border and underside loosely fibrillose. Hymenium waxy, 

 of a deeper color, by dryness rimose-parted. 



Upon wood and bark; common. Eff'used for several inches. 

 Not often perfect. 



3. C. AuBERiANUM,' Mout. Effused, adnate, very thin, sub- 

 membranaceous, snow-white, the border persistently floccose. 

 Hymenium becoming pallid, pubescent with minute brown bristles. 



On hickory bark. "Ohio, Lea." Berkeley, in Notices, No. 252. 

 At first orbicular, the whole floccosemealy, at length extensively 

 effused and confluent. This must be a curious thing. I have 

 never met with it. 



4. C. RADiosuM, Fr. Subrotund, membranaceous, adnate, 

 underneath appressed fibrillose; the border fringed with white 

 fibrile. Hymenium even, glabrous, alutaceous, contiguous. 



On rotten wood; common. Several inches in extent. 



5. C. FiLAMENTOSUM, B. & C. Effuscd, membranaceous; 

 border and underside soft-tomentose, fibrillose, pallid. Hymen- 

 ium pulverulent, ochraceous or somewhat olivaceous. 



Oil old wood and bark of elm. Subiculum consisting of soft 

 tomentose threads, on which the ochraceous or olivaceous pulveru- 

 lent hymenium forms a thin stratum.
