Perithecia cespitose, orange-red, nearly smooth, at length col- 

 lapsing. Ostiolum papilliferum minute. Asci clavate-cylindrical. 

 75-100 x 10-12 /i, filled with countless minute sporidia. 2-3 (mostly 

 2 J /i) x 1-1 J ft. In the early stages of growth, the asci contain 2-4 

 cylindrical bodies about 3 a thick and varying in length from 15 u to 

 nearly the entire length of the asci. These elongated bodies arc sub- 

 undulate and often appear distinctly multiseptate with the septa either 

 running square across or with their ends a little curved so as to give 

 the appearance of a series of hyaline, subglobose sporidia. but finally 

 these cylindrical bodies are filled with the minute sporidia. which at 

 length fill the entire cavity of the asci. Sometimes, instead of the 

 elongated bodies, some of the asci will be seen to contain one or two 

 scries of faintly-outlined, subglobose cells, which, also, are at length 

 tilled with the minute sporidia and disappear. The peculiarity here 

 noted has been observed in all the specimens on coniferous trees thus 

 far examined and we fancy we see the same Structure in the X. cu- 

 rurbitula. issued by Fries in his Scler. Suec, which we have had the 

 opportunity of examining.

Mycologists are not agreed as to the nature of the minute allan- 

 toid sporidia in this and the following species. Fi'ickel considered 

 them spermatia. Winter (in "Die Pilze") regards them as secondary 

 spores resulting from the germination of the true sporidia. In that 

 case, the asci should contain in the earlier stages of growth only the 

 larger 'true sporidia"; but specimens on the same limb of Phnts
