PiPTOCEPHALus REPENS Vail Tieghem. This species can be 

 easily recognized by the dichotomously branched conidiophores 

 and the chains of conidia on the uUimate l^ranches. The general 

 appearance reminds one of Sporodiiiia aspcrgillus. So far as I 

 know, this is the first time that it has been reported for America. 



Chaetocladium brefeldii Van Tieghem et Le Alonnier. 

 This is supposed to be parasitic on other moulds. It is known by 

 its verticillately branched sporangiophores ending in a long ster- 

 ile tip. The spores are borne singly on swollen parts of the 

 branches.
