in number, large, and colored. The only extraordinary thing 

 about them is that they are borne on basidia which are modified 

 and developed paraphyses whose bristles have become larger, 

 loncrer, fewer, and more erect. The development of the spores 



is similar to that described and figured by De Bary in his "Mor- 

 phology and Biology of the Fungi, Mycetozoa, and Bacteria," 



page 64, for C. amoj'phiim, Fr. 



The paraphyses branch only occasionally and the branches 

 are always given off considerably below the tip, from that part 

 which is still clear and hypha-like. Those branches which I saw 

 were short, but rather large, (see fig. b). 



Among the brush-like paraphyses I found numerous threads 

 which resemble the moniliform filaments in the hymenia of C. 

 aviorphiim, Fr. Upon each thread of this sort are from one to 

 six bead-like structures (see fig. c). The one on the tip is gener- 

 ally more constricted than the others. When there is only one 

 bead on a hypha It may become so much constricted from the 

 rest of the thread as to be almost separate therefrom. In this 

 stage it faintly suggests a spore. 



Having found some moniliform hyphae in C. Oakesii which 

 resembled those of C. amorpliuin, I examined C. amorphinn in 

 order to find, if possible, some trace of the bristle-brushes of C. 

 Oakesii. In this I was unsuccessful, and, so far as I know, these 

 bristly paraphyses may be considered the characteristic possession 

 of C. Oakesii. For this reason, therefore, as well as on account 

 of certain differences in external appearance, etc., I am convinced 

 that C. Oakesii is not, as had been supposed by earlier writers 

 and more recently by Mr. A. P. Morgan in his " Mycologic Flora 

 of the Miami Valley," "the same as C. ainorphtdiij' nor even a 



variety of the species. 



In Grevillea (iii, 172), Cooke gives a brief but suggestive de- 

 scription of the structure of C. Oakesii as seen in two Ameri- 

 can specimens which he examined. He speaks of finding " incip- 

 ient asci," " large sporidia," and " nodolose paraphyses," and 

 concludes that the "spicules," or bristle-like processes of the 

 paraphyses, are the stalks of conidial spores. 



This appears to be the first paper in which the paraphyses 

 with spicules were correctly described and their true nature
