450 COMPARATIVE MORPHOLOGY OF FUNGI 



tification is covered by a gelatinous hyphal layer which swells much in 

 damp weather. In the parts of the tissue lying beneath it, the hyphae of 

 the context branch fruticosely during the young stage and at their ends 

 cut off singly or in short chains, a large mass of thick-walled, ochraceous, 

 binucleate gemmae (Fig. 29 1 , 5 and 6) . The flesh of the fungus is streaked 

 dark and grayish by the large number of these gemmae. In the later 

 stages of development, at the formation of the hymenium, formation of 

 gemmae ceases (Seynes, 1874). The other species are confined to the 

 southern United States.
