[June 17, 



The recently discovered fungi of the Coal-measures are investigated, 

 especially the Pernosporites antiquiorum of Mr. Worthington Smith. 

 The author finds, in the specimens he has examined, including that 

 described by Mr. Smith, no traces of septa in the hyphge or of 

 Zoospores in the Oogonia. He concludes that its affinities are pro- 

 bably with the Saprolognise, and not Avith the Pernosporeee.
