This curious fungus belongs to a novel group of the Melan- 

 coniales, differing from all hitherto known in its chains of spherical 

 spores, and in the arrangement of its conidiophores, which in certain 

 cases are said to resemble those of Penicilliuvi. The spores arc^ 

 exceedingly numerous, and form dense masses which make it difficult 

 to see the conidiophores, but after washing them away one perceives 

 long delicate branched hyaline hyidue, on which are dense fascicles of 

 conidiophores in the form of spherical heads scattered here and 

 there.
