seem remarkable that this form should have been referred to 

 Dacryomyces, which is now well understood to- be a genus of Ba- 

 sidiomycetes. It must be remembered, however, that at the time 

 this species was described, careful microscopic studies of these 

 organisms had not been made and the reference to this genus was 

 probably based upon the slight superficial resemblance which 

 large sporodochia of this fungus have to the fructifications of 

 certain small species of Dacryomyces. 



Sphaeronema corneum C. & E. The next description of the 

 conidial stage which we have positively identified is under the 

 name Sphaeronema corneum C. & E. (1878). The original de- 

 scription is brief and one would scarcely think from reading it 

 that it applied to our fungus. It was said to have " cylindrical 

 perithecia." A study of authentic specimens on stems of Oeno- 

 thera, however, issued by Ellis & Everhart in N. A. F. No. 2074, 

 shows that there is no fungus on these specimens, either the one 

 in the herbarium of the Department of Agriculture or in the New 

 York Botanical Garden habarium, agreeing with the usual ge- 

 neric characters attributed to Sphaeronema. There are, how- 

 ever, small sporodochia of Hainesia present with typical spores 

 of this form. There is also found with the specimen of Pesiza 

 oenotherae E. & E., N. A. F. No. 846, a note on the label stating 

 that this species is accompanied by Sphaeronema corneum, E. & 

 E. on the same specimens. Here we also find well developed 

 sporodochia of Hainesia but no trace of a true Sphaeronema. 

 It seems certain, therefore, that the fungus to which Cooke & 

 Ellis applied the name Sphaeronema corneum is none other than 

 the conidial stage of Pczizclla lythri and its reference to Sphae- 

 ronema was evidently due to the superficial resemblance of the 

 sporodochia to the pyenidia of Sphaeronema; as has been already 

 referred to in describing the morphology of this stage (p. 144). 



Gleoesporium ? tremellinum Sace. This was found on 

 leaves of Acer campestris in Europe and first described by Sac- 

 cardo (1880). The long branched sporophores lead him to in- 

 sert the question as to its belonging to Gloeosporium. Later 

 (1884) he referred it to Hainesia as H. tremellina. His figures 

 (1881) and his description agree so well with the conidial form
