1 In comparing the descriptions, the great similarity between those of Dimeriella Olyrae 

 and Asterina fiimagina was noted. In response to a request for an opinion in the matter, 

 Dr. Stevens replied as follows: 



"The species as published by Dearness and Barth. is based upon specimen No. 190 of 

 my collection. My species, Dimeriella olyrae, is based upon my specimen No. 6770, but th« 

 two are co-specific and the publication of Dearness & Barth. clearly has the prioritf. 



"In the light of modern publications on this group, I believe that this fungus shouW 

 be placed in the genus Dimeriella of Spegazzini, and therefore suggest the following: 

 "Dimeriella jumagina (Dearn. a Barth.) Stevens, comb. nov. 

 "{.Astenna fumagina Dearn & Barth.) 

 "(Dimeriella olyrae Stevens.)"
