b. Growing on trunks. 



8. C. PYxiDATA, Pers. Pallid then alutaceous and subrufescent. 

 Trunk slender, glabrous, branched; the branches and branchlets 

 all cup-shaped at the apex ; the cupules proliferous-radiate at the 

 margin . 



On rotten wood; rare. Sometimes in clusters of considerable 

 extent, 3-5 inclies in breadth and height; the branchlets obconic, 

 even ; the cupules repeatedly verticiilate-proliferous, the terminal 

 ones dentate. 



9. C. CORONATA, Schw. Pale yellow then fawn color, divided 

 immediately from the base and very much branched; the branches 

 divergent and compressed or angulate, the final branchlets truncate- 

 obtuse at the apex and there encircled with a crown of minute 

 processes. See Plate II, Fig. i. 



On rotten wood; common. Repeatedly dichotomously or 

 verticillately branched and forming clusters sometimes several 

 inches in height and extent. Resembling in form the preceding, 

 but a distinct species. 



B. Spores ochraceous or cinna7non. 

 c. Growing on the ground. 



10. C. AUREA, Schaeff. Trunk thick, elastic, pallid, divided 

 into stout, straight branches, which are dichotomously very much 

 branched; the branchlets terete, obtuse, subdentate, yellow. 



On the ground in woods ; rare. Three to 4 inches high with 

 the trunk an inch in thickness. Resembling C. flava but very dis- 

 tinct from it by reason of the differently colored spores. 



11. C. FORMOSA, Pers. Trunk thick, elastic, whitish; the 

 branches very much branched, elongated, orange rose-color ; the 

 branchlets obtuse, yellowish. 



On the ground in woods; rare. Three inches or more in height, 

 the trunk an inch in thickness. 



12. C. INCURVATA, Morg. n. sp. Fragile. Trunk thick, fleshy, 

 white; branches ochraceous, dichotomously very much branched; 

 the branchlets spreading, somewhat flexuous, rugulose, the apices 

 dentate. See Plate II., Fig. 2. 



On the ground in woods; rare. Trunk white, an inch and a 

 half in height and i inch thick ; branches and branchlets ochra- 

 ceous, 2-3 inches longer, with an extent of 3 or 4 inches. The 

 peculiar feature is the spreading branches curving outward and 

 upward.
