On stripping otV the epidermis, the perithecia s()metiiM"s adhere; to

Apparently related to V. piistnlatu, Awd., hut the crowded osti- 

 ola are central in the disk. When the epidermis is torn away, the 

 pustules appear much like those of V. coUknli/.s, Wormsk. We have 

 seen no specc, and take the above diagnosis and remarks from the 

 Re])ort cited.

Pustules numerous, minute, covered hy the ejiidermis, which is

The very small size of the imstules, and the mimite, white, j)ulver-
