 Gard. Herb., 58810). 



31. C. Bambusae Burt, n. sp. 



Type: in Burt Herb., and Farlow Herb. 



Fructifications small, becoming confluent, effused, adnate, very 

 thin, tender, small pieces separable, cartridge-buff, even, not 

 shining, somewhat cracked, the margin free in some places; in 

 section 80-120 y. thick, not colored, with the hyphae about 2^ \l 

 in diameter, not incrusted, not nodose-septate, arranged longi- 

 tudinally along the substratum and sending out lateral branches 

 to form the hymenium; no gloeocystidia; basidia simple, 40 X 

 10 [l, with 4 sterigmata; spores hyaline, even, 14-18 X 8-9 n, 

 pointed at both ends, copious. 



Fructifications 1-3 mm. in diameter, becoming confluent over 

 an area 4 cm. long, 1-1 H cm - wide. 



On bamboo. West Indies and Venezuela. Very common. 



The small, cartridge-buff fructifications clustered together and 

 becoming confluent over the hard cortex of culms of bamboo and 

 the unusually large spores are good distinctive characters for rec- 

 ognition of this species.

 and pinkish buff to wood-brown in the herbarium, cracking into 

 areolae 2-3 mm. in diameter and with a distinctly radial arrange- 

 ment of the principal cracks frequently, more or less colliculose 

 with broad, slightly elevated granules, the margin narrow, fibril-
