Perithecia cespitose. ovate-globose. ^-J mm. diani.. dull rod. 

 densely tuberculose-granular. Ostiola not prominent, more or h-ss 

 distinctly stellate-cleft and finally collapsing slightly.. Asci sublanceo- 

 late. 7 o-80 x 10-12 a. without any distinct paraphyses. Sporidia sub- 

 biseriate, hyaline, oblong-elliptical. 3-septate, slightly curved, ends 

 obtuse, 18-22x7-9 /. The conidial stage is a Tubewuluria about 

 2 nun. high. bursting out in a seriate manner through cracks in the 

 outer bark, having an orange-red head and brick-red, stipitato base. 

 The perithecia originate from the lower or medial part of the stipitate 

 base, and finally entirely surround and overtop the orange-colored 

 heads of conidia, which are either entirely hidden or remain partially 

 visible in the midst of the dense clusters of perithecia. Conidia oblong- 

 cvlindrical. hvaline. continuous, 5-7 x2i n.

There is no shadow of difference in the asci and sporidia, at least 

 as the two are represented in Rav. Fungi Car., between Ifectria 

 oiirigera, B. c\: Kav., and N. polythalama, Berk., and if, as there is 

 no reason to doubt, the specimens there distributed are authentic, the 

 two species are the same, and, in that case, tho specific name, prtlytlnl- 

 inttt. would have precedence.
