spores borne on niinntc pellucid teeth, along the lower part 

 of ascending fertile branches. vSpores filiform, hyaline, con- 

 tinuous, usually coiled about three times; the thread 70-9C 

 mic. in length, and about i niic. in thickness. (Fig. 2.) 



Growing in small patches on old bark of vSassafras. While 

 the spores in this species are similar to those in //. olivaceiis, 

 the hyphce are very different ; the ascending greenish-pellucid 

 fertile branches arc similar to the creeping hyplue, and some- 

 times they are branched.

Growing on old wood and bark of all kinds, and very com- 

 mon. The ascending, flexuous branches rise above the stra- 

 tum of spores ; the hyphse are twice as thick as the thread of 

 the spores ; there is often an intervening, short, hyaline pedi-
