 no cystidia.

Crepidotus rhizomorphus Burt, n. sp. 



Dried fructifications 5-7 mm. broad, membranaceous, sessile, 

 pinkish buff of Ridgway, glabrous, even, the margin entire; 

 lamellae radiating from a central point, ventricose, close, snuff- 

 brown; spores ochraceous under the microscope, even, 6-7 X 

 4t-4%\l; a flattened rhizomorphic strand about 1 mm. broad, 

 bone-brown in color, runs up the outside or within the grass culm. 



On culm of an undetermined grass, Hawaiian Islands, F. L. 

 Stevens, 940, type (in Stevens Herb.). 



Two fructifications were present at about a centimeter apart; 

 one was supported by a short, lateral branch of the rhizomorph, 

 and the other had that portion of its upper surface in contact 

 with the culm adnate to the latter, and the remaining surface 

 free. This species is noteworthy by the thread-blight habit of 

 its rhizomorphs.
