BURT THE THELEPHORACEAE OF NORTH AMERICA. XIII 13 



Fructifications coriaceous, soft, resupinate, at first circular, 

 pezizoid, and with the thickened, paler margin slightly upturned,, 

 at length confluent, effused, and with the hymenial surface 

 merulioid by the elevated confluent margins and reticulate 

 veins, drying deep olive-buff to drab; hyphae with walls gelatin- 

 ously modified, nodose-septate; basidia simple, with 2-4 sterig- 

 mata; spores white in spore collection, simple, even, 8-11 x 6-6 

 It. 



Fructifications at first 1-3 mm. in diameter, finally confluent 

 over areas 3-8 X 3-5 cm. 



On bark of decaying limbs of frondose species in low woods. 

 Louisiana. November to June. 



Although the young fructifications of C. tremellosa are decidedly 

 pezizoid in aspect, yet, in the specimens seen by me, these small 

 fructifications are in such close proximity to resupinate confluent 

 masses of the same color that the resemblance to a Merulius 

 is the more striking. 



Specimens examined: 

 Louisiana: St. Martinville, A. B, Langlois, 2620, 2670, aw, 694 



(in N. Y. Bot. Gard. Herb., and Mo. Bot. Gard. Herb., 61681); 



C. G. Lloyd, 2^02 (in N. Y. Bot. Gard. Herb, and Burt Herb.). 



SOLENIA

 Pflanzenfam. (1:1**): 129. 1898; Rea, Brit. Basid. 701. 1922. 



Fructifications coriaceous or membranaceous, sessile or nearly 

 so, cylindric or turbinate, gregarious, fasciculate, rarely solitary, 

 but not joined together except by confluence, seated on a super- 

 ficial, felt-like, floccose and sometimes fugacious mycelium; 

 basidia simple; spores white or colored. 



The type species is Solenia Candida Pers. 



Solenia is closely related to Cyphella but differs from the latter 

 by more numerous and less scattered fructifications which are more 

 cylindric in the case of most species, and in having the gregarious 

 fructifications seated on a more or less manifest mycelium. The
