Gard. Herb., 9852).

 Soc. Bot. Jour. 27: 128. 1890. 



Type: in Kew Herb, and Farlow Herb. 



Fructifications effused, adnate, rather thick, small pieces 

 separable, becoming chamois-colored in the herbarium, ceraceous, 

 even, sometimes cracking in drying but the cracks not running 

 together, showing the Isabella-colored tissue on the sides of the 

 cracks, the margin thinning out; in section 200-400 p. thick, 

 Isabella-colored, 2-layered, with a broad layer next to the sub- 

 stratum of brown hyphae 2-3 ji in diameter, not incrusted, not 

 nodose-septate; spores hyaline, even, subglobose, 3-4 y. in di- 

 ameter or 4 X3(i. 



Fructifications recorded as ' ' spreading for several inches/ ' The 

 fragmentary pieces in herbaria are 2-3 cm. long, 1 cm. wide. 



On bark and decaying wood. Louisiana, Texas, and West 

 Indies. February to June. Rare. 



The fructifications of C. subcontinuum resemble in general 

 aspect, thickness, and consistency those of C. confluens, but are of 

 different structure from those of the latter and are sharply dis- 

 tinct by the colored substance of the interior. The Louisiana 

 specimens are doubtfully referred to this species.
